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’ private bookcase. Whenever Billy opens the classic books inside, he can hear sounds coming from the island in the middle of the lake. The clash of swords. The twang of arrows. The dialogue of characters. 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?

Before long, Dr. Libris’ island is populated by some of the most famous characters in all of literature: Hercules, Robin Hood, Maid Marian, The Three Musketeers, Tom Sawyer and Pollyanna. When these characters mingle, their plot lines get mixed up (and complicated by the arrival of a few comic book heroes and villains).
