Varick's Quest - Devya's Children, #4

Genetically altering humans is illegal .But Varick and his siblings-Devya's Children-exist. He's been born and bred to be the perfect soldier, but he can't be everywhere. If one counts each of his siblings plus Danielle Matheson, the list of people Varick wants to protect stretches from coast to coast. The more he gets to know Danielle, the more she comes to mean to him. Meanwhile, somebody has captured Nadia and wants to sell her to the highest bidder.
Varick's lifelong quest has been to free her from their father, Dr. Dean Devya. But nobody knows where to find Nadia, except Dr. Carnasis, and she's a captive as well. Danielle and Jillian have also disappeared. Varick might be able to pull off one rescue, but can he save them all?
