The Devil Within by Tanya Nellestein

Sometimes you have to go to dark places before you can truly find the light.

Sarah Darcy has created the life she always wanted with her dream job in London, as far from Australia as she can get. However, all she’s ever wanted was to love and be loved. She thought she’d found it in bad boy biker, Alex Riley; until he ripped her heart out.
Unwanted his whole life, Alex went from foster child to an outlaw and enforcer with The Devils MC. He never went looking for love, never thought he deserved it, until he found Sarah. To keep Sarah safe, he ended the relationship. But he couldn’t stay away, not forever.
Alex has come to start his life over as well. But he’s running from a dark and violent past that will not let him go alive. Forced to run for their lives across Europe, being chased by a biker gang hell-bent on revenge. With no one else to turn to, can Sarah trust Alex, let alone love him again?
