Reading while school is out is critical—if kids don't read over the summer, they can lose two to three months of reading skills. It's important to encourage students to pick books that excite them even when they aren't in school. We made it easy to keep those reading skills on track all summer long with this supersized series collection. There's truly something for every type reader in this book list filled with firsts from some of our most popular series of all time. Packed with a hugely diverse selection, elementary and middle school readers will love discovering new favorite characters like Harry Potter, Captain Underpants, Judy Moody, and Jack and Annie that will stay with them all summer long and for years to come. Summer reading has never been so much fun!
