If the delivery had been a demonic bowling alley or a mermaid's grotto, Ivy would have sent it away. She has standards, after all. But she can't refuse a magical Library, especially when they've gone to the trouble of including a wheelchair ramp. They say that on the Internet nobody knows you're a dog, but somebody knows fourteen-year-old Ivy is an orphan, that she sells her paper-writing services to lazy college students, and that her imaginary friends are unhappy being stuck in the mural on the wall of her Alaskan home. Himitsu refuses the Library, becoming angry enough to attack the delivery people with his bamboo sword. They won't tempt him with books, any more than his mother has been able to tempt him into leaving their apartment during the past two years. He has all he needs: video games, online forums, and his virtual girlfriend Moe. Well, almost all. His dad's death has left a hole in him, which is why when he receives text messages saying the Library can bring back the dead, he changes his mind. Moe tries to warn him about the danger, but what does she know, anyway? Now, having been lured into the Library and having foolishly brought their imaginary friends with them, Ivy and Himitsu find those friends are trapped. The teens have a choice: fulfill the Librarian's odd and painful demands in hopes of rescuing their friends or go back alone to their small, boring lives, knowing they've failed the only ones who really believe in them.
