Harry never misses a step, until the night he unknowingly hooks up with the assassin he's been ordered to catch. Winter is a master manipulator, a ruthless assassin with a chilling elegance and icy eyes that seem to pierce through the soul.

In a world of secrets, betrayal, and bloodshed, Harry finds himself completely captivated by the danger he seeks to eliminate. The cat and mouse game begins, blurring the lines between duty and desire. // "Because we're still doing this the easy way." Harry muttered, his hand flexed on the back of my neck. I gasped when he used my throat to pull me towards him. He spun me around, shoving me back forcefully so my back hit the wall. "I don't want to have to do it the hard way." His chest was against mine to keep me further restrained, my wrists were pinned against the wall above my head. "I don't wanna have to be the bad guy." "What are you going to do?" I asked him, swallowing, feeling his palm wrapped tightly around my throat, but not enough that I was choking, just enough that I could feel the pressure. "Are you trying to choke me, Harry?" I cocked my head to the side, grinning through my blood stained lips. "C'mon... you know I like it."

Fern Jones, a venerable and ambitious aspiring author from California, moves to England, determined on keeping her unsettling past on the pages of her journal, stumbles across Harry, a brooding and intolerant owner of a bookstore. Desperate to silence her inevitable thoughts, she latches onto him in the hopes he'd make her forget for that one night. With Harry still engaged in old habits, and emotionally unavailable, Fern can't help but wonder just what hides beneath the surface of his barbarous ways and his inability to let people close to him. Only when her curiosity compels her into crossing Harry's boundaries- she realises Harry is more than just a bookstore owner, and much more fearsome than she would've ever imagined.
