All 20 year old Daisy Haites has ever wanted is a normal life, but it's just not on the cards for her. Raised by her older brother Julian since their parents were murdered in front of them 12 years ago, Daisy hasn't ever lived beyond the watchful gaze of her gang lord brother. But Julian's line of work means that Daisy's life is...complicated. And things don't become any less complex when she falls hard for Christian Hemmes, the beautiful and emotionally unavailable boy she's been involved with for the last few months, who also happens to be one of the few men in London who doesn't answer to Julian. Christian's life is no walk in the park either, being in love with his best friend's girlfriend and all... He's happy enough to use Daisy to throw off the scent of his true affections, that is until she starts to infiltrate those too.

As their romance blossoms into something neither were anticipating, Daisy, Christian, and Julian each have to come to with the fact that in this life everything comes at a price. As their relationships intersect and tangle, they all learn that sometimes life's most worthwhile pursuits can only be paid in blood.
