New from the author of Escape from Mr. Lemoncello’s Library and coauthor of the I Funny series with James Patterson! Celebrate the power of imagination with this action-packed New York Times best seller that shows that sometimes the real story starts after you close the book!

What if your favorite characters came to life? Billy’s spending the summer in a lakeside cabin that belongs to the mysterious Dr. Libris. But something strange is going on. Besides the security cameras everywhere, there’s Dr. Libris’s private bookcase. Whenever Billy opens the books inside, he can hear sounds coming from the island in the middle of the lake. The clash of swords. The twang of arrows. Sometimes he can even feel the ground shaking. It’s almost as if the stories he’s reading are coming to life! But that’s impossible...isn’t it?
