Liam Wolfson, the professional assassin, is dead. His new persona, Jack Hammerson, lives in a small town in Colorado, happy helping out as many of the townsfolk as he can. It’s his way of working toward some kind of redemption for his sins. Until one night when an amnesiac woman falls into his arms, calling out his old name...

Kara remembers nothing about her previous life, only brief glimpses of an old lover and their time together... but she knows her fate is entwined with Liam's. Then there’s the familiarity with all things Valkyrie and Valhalla. She worries she might be going crazy.

Liam has worked hard to hide all traces of his old life but Kara rips old wounds open as their old feelings for each other come rushing back. But it's not just Kara who's come to town looking for answers. When mercenaries arrive looking for Liam, he’ll need Kara to remember what she’s capable of if either of them is going to survive...
