Amy Prochenko has spent most of fifth grade avoiding both the bully Katilyn Walker, whose bark is as bad as her bite, and Sean Gorman, the only kid less popular than Amy. As if life isn't hard enough, along comes Sherlock.

After escaping from a research laboratory, all Sherlock wants is to be an ordinary dog. But Sherlock is anything but normal: he can talk. And when he asks Amy for help, she says yes. But Amy may have bitten off more than she can chew! Soon she finds herself tangled up in dangerous schemes and hanging out with people she never would have before. For the first time, thanks to Sherlock, Amy's popular!

Even better, Sherlock is the best friend she's wanted. But Amy's not sure she can save him. Will this dog ever have his day?
