Shadowed in Sunshine (en Inglés) - T.K. Drake

Lucy Sommers has always made the most of whatever life has thrown her way. When she's handed a trust from an anonymous source, she's determined to dig deeper, even if it takes her across the country. In a whirlwind of events, she finds herself wrapped up in a life she never could have imagined. Nothing could have prepared her for catching the attention of Sasha Taranov. He's dangerous, the kind of man that should send her running for the hills, but she can't stay away. As their connection deepens, she knows she will always belong to him, but will her light be able to withstand the darkness within his soul?  

Sasha Taranov's soul is stained by his inheritance. Although he accepted his fate long ago, he relishes every moment of freedom before darkness comes calling again. He's never allowed himself to dream of a future of anything except violence, until he meets her. Lucy Sommers. She's a ray of light, permeating through every crack of his hardened heart, slowly breaking down his walls one by one. He knows he shouldn't trust her, and that he should let her live her life free from his shadows. But as the truth slowly comes to come to light, he realizes there's nothing he wouldn't do to keep his Sunshine.
