Action meets romcom. Assassin Maisie Baxter meets her match in mysterious hitman, Agent Perseus, as the two rivals team up to uncover a conspiracy.

Maisie Baxter has a particular set of skills honed over a very successful career. She’s determined not to let being the number one ranked hitman at the UK’s second-best agency get in the way of her having the social life of any other 30-something Londoner, but it’s tough to date when your hours are extremely unpredictable and you can’t share any details of your day.

So she can't tell her friends about the guy that keeps showing up on her missions. Will. He's cute, really cute, and he insists he has crucial information for her.

Maisie is sure Will works for the competition but it soon becomes clear that a much greater danger stalks them both. And they're going to have to put aside their professional rivalry – and their building sexual tension – if they have any hope of uncovering the conspiracy that goes all the way to the top.
