XV (Fifteen) (War of Roses 1)

Mistakenly kidnapped as part of a years-long family feud, Ellen must do whatever it takes to protect herself from her cruel captor, Mischa. Will he show her mercy and kindness — or will he break her?
WHEN HATE BECOMES OBSESSION…
Mistaken for her beautiful half-sister, Ellen Winthorp is taken captive by a madman who declares that she will be his "fifteen": the fifteenth victim of a vicious mafia blood feud.
Armed with only her instincts, Ellen must resist her captor for as long as she can—which is easier said than done the more she's exposed to the complex man beneath the beast. Because Mischa Stepanov isn’t a mindless monster—he’s a wolf, and she’s the unwitting doe caught in his midst.
Unraveling the torment of his past may be her only hope of salvation... Or the secrets uncovered may destroy them both.
