Philomene Doucette is a made-to-order assassin, and death never looked so good. Orphaned and brain-washed from the age of six, by Beau Dupree, a C.I.A spook, she is a beautiful, empty killing machine, fractured from systematic abuse. Philomene is given her most important assignment yet: executing Haruto Mori, the leader of a deadly Japanese clan. To conceal her identity, Philomene is smuggled into Japan under the guise of being a sex worker and is presented as a gift for Haruto. Philomene's mission to kill Haruto becomes an inner battle as she struggles between her conditioning, the affection she feels for Haruto and her increasing desire for Tadakai, her CIA handler. When Haruto is unexpectedly murdered by another assassin, Philomene uses her deadly training to find answers. She learns of a shocking government plot for mass murder at an upcoming Yakuza Summit—where Tadakai will be in attendance. Philomene rescues Tadakai, and together they find a haven in a remote, abandoned farmhouse. As they forge a deeper connection, the two make a life-changing decision to leave this dangerous lifestyle behind to create a new life together...but their past misdeeds will not be absolved without exacting bloody sacrifices.
