The Island of Dr. Libris is a book about a twelve-year-old boy named Billy. He is going up to Lake Katrine to spend the summer with his mom. His mom is renting a cabin at a cheap price from a professor at her college. Billy wishes he could stay with his fun dad. Instead, he has to stay with his mom in a place where fun is hard to come by, and when he breaks his iPhone it makes it even worse. Finally, his mom suggests he read some of the books from Dr. Libris' bookcase. He takes her up on her offer, but first he has to find the key. Using a riddle inscribed on the bookcase, he manages to find it.

Now able to get into the bookcase, he decides to read a book called, The Labors of Hercules. There is a picture on the bookcase that shows Hercules fighting a big rock guy. Feeling inspired, he turns to the page in the book where Hercules is fighting that character.  Billy sits down and starts reading. Suddenly, he hears something from the island and realizes that he is hearing exactly what is happening in the book. Rushing outside to see if he can see something, he notices a huge rock out there. At least he thinks it's a rock until he sees it move. Billy goes inside, closes the book, and the noises suddenly stop. Wondering if he is going crazy, he decides to try again tomorrow morning. Is Billy imagining things, or is someone playing a prank? Or craziest of all, could this actually be real? Find out for yourself in The Island of Dr. Libris!
