Warrior by Beth D. Carter

Warrior
Although Church is a twin, she’s always felt isolated from her sister, Cherry. Taking over the mechanic garage across the street from The Forgotten Rebels MC ensures that she’s never alone, even though her haunted past makes it difficult for her to trust another person.
Darrell McBryde lost his leg on active duty, changing not only his life but his mind on the club’s drug running business. Taking a stance against it, however, has put him at odds with the other members. In a world he once knew, suddenly he’s a stranger.
Both outcasts, Church and Darrell forge a tight friendship, one that eventually shifts into something deeper. But just as she’s about to reach out to take a chance, tragedy strikes, testing Church’s faith that love and happiness are hers for the taking.
