Best Adventure Book Series for 9 and 10 year olds

Nurturing a passion for reading can become harder and harder as your child gets older and begins to interact with competing media (we're all battling with Nintendo Switch games and YouTube videos, right?). But the truth of the matter is there are so many exciting books for the age bracket of 9–10 and all it takes is finding the perfect series to get your child hooked.

Children this age especially love adventure stories through which they can vicariously have their taste of action, mystery solving and even magic. Series also help, as they can easily dip back into a story full of familiar characters who they are already invested in.

Here are some of Toppsta’s top-reviewed adventure series for readers aged 9+, including nature adventures like The Polar Bear Explorers' Club or The White Giraffe Series, magical epic adventures like Amari and the Night Brothers, and mysteries like Adventures on Trains.
