Matchmaking for psychopaths

Like every good romance, this story ends with a wedding. And like every good mystery, it begins with a murder... When Alexandra's fiancé runs off with her so-called best friend, her life veers sharply away from the romance films she's obsessed with. She's worked so hard to get her fairytale ending after the horrors of her past, and despite this setback, she's determined she'll still find her happy ever after.
To distract herself, Alexandra tries to focus on her job where she has a secret specialty : matchmaking psychopaths. But in losing the two people closest to her, she's unignorably lonely. So when a hot, overprotective new client wants to date her, and another gorgeous new client wants to become her best friend, she can't help but find the attention a little comforting. Things take a turn the day a human heart is left on Alexandra's doorstep.
But is the culprit one of her new admirers, or has a monster from her past returned to destroy her happy ending forever ?

To escape her relationship troubles, Alexandra throws herself into her job where she works as a matchmaker for psychopaths - a label that the clients themselves are unaware of - and becomes entangled with two of her most recent clients, both of whom have mysterious pasts that inspire Alexandra to breech work protocol and spend time with them outside of the office.
