Operative Jacqulyn Foster is drowning in the horrors she’s perpetrated for the "greater good," but she’s determined to prove her worth on the next mission and to outrun the shadows that haunt her.
Their latest mission: go undercover in a Nazi concentration camp to retrieve a brilliant doctor who may hold the key to curing cancer. Landry and Foster must race against time to extract the doctor before she’s executed or the cure-and their lives-will be lost. But with every move a deadly risk and their partnership under strain, can they save the future, or will they fail, damning their past, present, and future?
