When her cell phone rings, Giselle Cutler answers it—and finds herself speaking to a dead woman.

As Giselle and her partner Marta Perry get ready for the birth of their baby, the last thing they expect is to be drawn into another mystery. But there's been a horrible mix-up with identification of a body found in the bay, and Marta's supervisor Chrissy Burton is very much alive and desperate for their help.

Intrigue turns deadly as they uncover illegal organ transplants, black market sales, and ties to international terrorism. The killer is willing to do anything to keep the public from knowing how the transplant system really works, even if it means killing Giselle and Marta.
