She is wildly unpopular.

She is the target of prissy Kaitlyn Walker's social torments.

And everyone thinks she and the dweebiest boy in class are dating.

Then one day Amy meets Sherlock, a dog who is on the run from a university lab. Sherlock is not like other dogs: He can talk, and he's smarter than most of Amy's classmates. And he needs Amy's help. Suddenly Amy finds herself doing crazy things she'd never imagined, finds her life full of danger and excitement, finds herself becoming -- of all things -- popular.

Best of all she finds in Sherlock the sort of friend she's always longed for, the sort of friend who will sacrifice anything for the sake of the friendship, the sort of friend she must rescue no matter what the cost.
