A realistic YA thriller with tragedy at its heart, set at an indeterminate point in the future: Cory Doctorow meets Julie of the Wolves, with a dose of Super-Sad True Love Story.

Nano Miller has spent her entire life on Dog Island, a sanctuary for world's last surviving canines and the testing ground for their robotic replacements. Every year, Nano gets a new and improved model. Now that her friendship with Wolf - a boy she's known forever - has turned romantic, she's certain she never wants to leave.

But when Dog Island's biggest celebrity supporter, movie star Marky Barky, arrives for his annual visit, Nano discovers something that shouldn't exist: a real live puppy, tiny and magical. Unable part with it, Nano now finds herself on the run. She knows that the puppy could destroy her family, Wolf, and even the Island itself.

Yet her harrowing fight for their survival sparks a belief that it might just save them all.
