In this sequel to Perfected, Ella has escaped to Canada, but is now trapped in a refugee house for pets, the genetically engineered girls bought and sold as companions.

Freedom comes at a cost...

Ella was genetically engineered to be the perfect pet-graceful, demure...and kept. In a daring move, she escaped her captivity and took refuge in Canada. But while she can think and act as she pleases, the life of a liberated pet is just as confining as the Congressman's gilded cage. Her escape triggered a backlash, and now no one's safe, least of all the other pets. But she's trapped, unable to get back to Penn-the boy she loves-or help the girls who need her.

Back in the United States, pets are turning up dead. With help from a very unexpected source, Ella slips deep into the dangerous black market, posing as a tarnished pet available to buy or sell. If she's lucky, she'll be able to rescue Penn and expose the truth about the breeding program. If she fails, Ella will pay not only with her life, but the lives of everyone she's tried to save...
