Dark Bastard by India Kells

To find the light, he must confront the darkness.

Sam Sarkhan has had enough. Enough of life, enough of struggling with his demons every day, enough of pretending that everything is okay. Even though his time as a soldier taught him not to give in until the mission is over, he decides to end it all on New Year’s Eve. A final call to his brother shows him he’s not the only one suffering when he misdials and reaches someone who seems as lost as he is.
Deciding to put off ending it all until he’s sure Ellie is going to live, Sam is left reeling when his darkest nightmare crashes back into his life. In order to save Ellie from the monster that is his father, Sam must make a deal with the devil.
With his heart on the line and his soul in tatters, Sam must decide if he’ll take an ultimate chance on love, or if his demons will drag him under for good.
