Heart Thief by Skylar Sweeney

VERY IMPORTANT NOTE: Heart Thief has “gone gay” and is now an LGBT romance! Previously published as m/f, this series (which was renamed as Blood Brothers to keep things clear) is now LGBT with m/m main characters! This is the way it was originally written, but for marketing reasons was originally published as m/f romance. So happy to have it back to what it was always meant to be–as gay as the fabulous author!

They say love conquers all, but is it more powerful than revenge?

MASON
A decade ago, Rex stole my little brother’s heart in a literal sense, and I’ve never forgiven him for taking my best friend’s transplant. When peeing on his doorstep and breaking into his house to leave rubber snakes behind doesn’t quench my thirst for vengeance, I decide to take things to another level by stealing his new replacement for the heart that is failing once more. But if I’d known ahead of time that Rex used to kill people for living, I might have thought twice about my plans…

REX
I know what it’s like to live on the dark side, and there’s nothing I love more than watching Mason, my beautiful good boy with a vengeance, try to play bad. When he infiltrates my company, I’m perfectly happy with the idea of my best frenemy as my new assistant, stealing my heart away… at least until I realize the love of my life is actually after the heart transplant that I need to survive.
