Abby and Dean have a new purpose to destroy Ostrander and ULTRA, but Ostrander has a new ally-another program subject specially trained to hunt down rogue operatives. Grant Shaw doesn't know ULTRA's secrets or the truth about Abby-all he knows is that he's going to find her and put her down. Abby may have finally met an opponent she can't beat...but Grant is starting to ask questions about the program, and that never ends well for a throwaway operative...
