One of the easiest ways to keep kids reading, especially during the summer, is to get them hooked on a great book series.

When I was eight, I spent an entire summer flying through The Boxcar Children. Each day, I’d settle into my blue bean bag chair and I would emerge an hour or two later triumphant that I had solved the mystery alongside the Alden siblings.

After that, it was The Babysitter’s Club (any other Mary Anne fans?) and Nancy Drew. I loved the feeling of walking out of the library with a stack of books, knowing I had days of adventures ahead.

There was something comforting about finishing a book and already knowing exactly what I’d read next. I didn’t have to say goodbye to my favorite characters; I just had to keep reading to see what they’d do next.

Now, I see the same thing in my own kids. They’re drawn to book series just like I was—and they’re not the only ones. There’s a reason series are so appealing to young readers…and why they’re such a powerful tool for growing a love of reading.

Why Book Series are so Good For Kids

Reading is hard work—especially for struggling readers and young kids who are still building their reading skills. A good book series makes reading easier and more enjoyable by giving kids something familiar to return to again and again.

Here’s why book series are such a powerful tool for growing readers:

Increases comprehension
Reading a novel means keeping track of a lot—characters, settings, plots, and themes. But with a series, once kids are familiar with the world of the first book, they don’t have to start from scratch each time. They can carry over what they already know, which makes it much less intimidating to start a new book.

Develops fluency
The more kids read, the better readers they become—and research shows that kids who read series tend to read more books. When a child enjoys the first book, they’re often eager to dive into the next…and the next. This repetition strengthens word recognition, builds vocabulary, and supports overall reading fluency. (Bonus tip: audiobooks are also a great way to boost fluency!)

Builds confidence
Reading a full book—let alone several—feels like a big win to a kid. When they can say, “I read all five books in this series,” they feel proud and see themselves as capable, confident readers.

Gets them hooked on reading
Book series are kind of like Pringles. Once you read one, you just can’t stop! We want to know what is going to happen next to these characters that we’ve come to know and love! And that’s exactly what we want where reading is concerned.

So, whether you’re looking to keep kids reading this summer or you’re stocking up for the school year, here are some of our favorite middle grade chapter book series.

Middle Grade Chapter Book Series Kids Love

A note about age recommendations: I’ve included minimum age recommendations for the books below, but they are simply that…recommendations. You know your child and what they can handle regarding content and complexity, so feel free to disregard them as you see fit. My seven-year-old has enjoyed a lot of the books below as read-alouds, but I think some younger kids like him may struggle to read them independently.

Fantasy

Ranger's Apprentice Book Cover

Ranger’s Apprentice (12 books)

John Flanagan | Ages 9+

My oldest son picked up this series last year, and he was immediately hooked. What’s it about? Think medieval adventure meets secret spy training. Tons of action, clever strategy, and a good dose of humor to keep things from getting too intense. Now he’s convinced his younger brother to read them, too. Now he’s reading the spinoff series: The Royal Ranger series and Brotherband.

The Menagerie (3 books)

by Tui T. Sutherland & Kari Sutherland | Ages 8+

If you read and loved Wings of fire, then check out The Menagerie series. It has some Fablehaven vibes, with a hidden preserve for magical creatures and three kids racing to keep it a secret. This was the FAVORITE series of all three of my boys last year (ages 7-12). Tip: the audiobook is included FREE if you have an Audible membership.

Wings of Fire (15 books + 4 graphic novels)

Tui T. Sutherland | Ages 8+

Dragons. Prophecies. Epic battles. This series has everything that my adventure-loving, imaginative kids love. My middle son was the first one to pick these up, and now he’s gotten both of his brothers reading them. Each book tells a different dragon’s story in a vast fantasy world.. They also have graphic novel versions of some of the books, which makes the story more accessible for my seven-year-old.

Gregor the Overlander (5 books)

Suzanne Collins | Ages 8+

You probably know Suzanne Collins from The Hunger Games, but before that, she wrote Gregor the Overlander. In this series, Gregor and his little sister, Boots, fall into a hidden world under New York City filled with giant bats, rats, and an epic quest to find their dad. Boots steals the show in this book, and my boys have loved listening to it together.

Percy Jackson and the Olympians (5 books)

Rick Riordan | Ages 9+

When I taught middle school, I could not keep the Percy Jackson books on my shelves, even when I bought multiple copies. They’re fast-paced, fairly easy reads about modern teens who find out they are half Greek god, and the chapter titles alone are hilarious (like “I Accidentally Vaporize My Pre-Algebra Teacher”—how can you not keep reading after that?).

Already read Percy Jackson? Did you know that Rick Riordan opened his universe up to other authors to write companion books focusing on other cultures’ mythologies? My son picked up The Storm Runner and loved it!

Chronicles of Prydain (5 books)

Lloyd Alexander | Ages 9+

I LOVE these books. I have listened to the entire series twice, and I never get tired of sweet Gurgi, sharp-tongued Princess Eilonwy, and the prone-to-exagerration Fflewddur Fflam. Don’t let the fact that this was published in 1964 make you think it’s out-dated. It’s classic fantasy at its best: a humble hero on an epic quest to save his world, surrounded by his loyal, if quirky, friends. It’s a more difficult read, but the audiobooks are phenomenal, so it’s a great road trip listen.

Harry Potter (7 books)

J.K. Rowling | Ages 8+

Do I even need to sell this one? Harry Potter is one of the most popular YA series ever, and for good reason. I’ve read them all multiple times and even visited some of Rowling’s inspiration spots in Edinburgh a few years ago. (Potter nerd? Yes, yes I am.) If you’re unfamiliar, keep in mind that the books get darker as they go, so proceed with caution. During the pandemic, I read the first three aloud to my older boys, but we took several years to read the later books with gaps in between while they got a bit older.

Mystery

Mr. Lemoncello’s Library (6 books)

Chris Grabenstein | Ages 8+

This wacky, fun-filled series is basically Willy Wonka meets Escape Room! We blew through them as a family read-aloud and had so much fun trying to solve the puzzles and riddles that are peppered throughout the books. It’s fast-paced, high-interest, and one of my top recommendations anytime someone asks me what book to get their 8-12-year-old kid.

Framed! (3 books)

by James Ponti | Ages 8+

This is another series we listened to last summer on our family road trips. It’s the action-packed mystery about Florian Bates, the only kid on the FBI director’s speed dial (and several international criminals’ most wanted lists) all because of his Theory of All Small Things, a.k.a T.O.A.S.T. This was fun for the whole family to listen to, and was a close runner-up for my kids’ favorite book series of the year.

City Spies (5 books, ongoing)

by James Ponti | Ages 9+

By the same author as Framed, this action-adventure series is like James Bond for kids. It’s about five kids from all over the world who get recruited to a special school for spies. I’ve only read the first book in the series, but it’s definitely worth a try!

FunJungle (7 books, ongoing)

Stuart Gibbs | Ages 8+

Full disclosure: I haven’t read this one, but when I asked my 13-year-old what his favorite books series are, this was in his top three. According to him, they are not-too-serious mysteries involving animals in a zoo, with lots of humore and some good twists to keep things interesting. He’s actually reading the most recent one (All Ears) currently, and it’s got me wanting to start the series myself.

The Mysterious Benedict Society (4 books + prequel)

Trenton Stewart | Ages 8+

These books about a group of gifted kids who are recruited to stop an evil mastermind are brilliant. They’re full of quirky character and fun puzzles to solve, and are especially good for advanced readers who need a challenge but aren’t ready for “advanced” content (if you know what I mean). We read the first two aloud as a family and my boys loved them…and may have become slightly obsessed with Morse code for awhile.

Science Fiction

The Wild Robot (3 books)

Peter Brown | Ages 7+

If you haven’t read the Wild Robot yet, go request it from the library right now. Sorry to be bossy, but I think every kid should read this book. It seems like an odd premise: a robot that gets stranded on an island and befriends the animals there. But it is completely charming, and surprisingly deep. It’s the perfect bedtime story, engaging but also somehow soothing. My boys all loved this series, and the movie, too! I think the first book is the best of the bunch, but they’re all worth reading.

Realistic Fiction

The Penderwicks (5 books)

by Jeanne Birdsall | Ages 8+

This sweet (and funny) series about four adventurous sisters is absolutely charming. Think Little Women, but younger, and more modern. I haven’t read them to my boys (they’re not really the target audience), but I adored this series myself, and I recommend it to every girl-mom I know.
