Chris Grabenstein, author of the New York Times bestselling Escape from Mr. Lemoncello’s Library and coauthor of the I Funny series with James Patterson, celebrates the power of imagination with this action-packed adventure 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? Look for brand-new BONUS material in the paperback, including a GALLERY of literary characters, a discussion guide, a behind-the-scenes look at Chris’s process, and more!   “A wonderful tale. . . . A complete original.” —James Patterson   “Effortlessly readable and a whole lot of fun.” —Booklist   “A science-based variation on the theme of fictional characters being brought to life. [A] satisfying read.” —Publishers Weekly Read Less
