Restored in Devotion (en Inglés) - T.K. Drake

Blanche Sinclair is a powerful woman who knows what she wants and has never been shy about going after it...until now. With all of her children settled and building families of their own, it's the perfect time to finally give in to the pull of her new paramour and commit fully to love again.

Ivan Taranov might be the father-in-law of her eldest son, but he's also caring, understanding, and forged of steel strong enough to handle her fire without being burned. He's what she's been yearning for, but she still has one foot firmly planted in the past. Because before there was Blanche Sinclair, there was...

Blanche Bedford, a new college graduate, defies familial expectations to move to a new city for a career of her own. With her parents' bemused blessing, she's ready for anything life can throw at her...until she meets him. 

Henry Sinclair Jr. is broody, misogynistic, and her new boss. He refuses to take no for an answer when their energies collide. His own demons chase him into Blanche's arms, but instead of being consumed by her, their toxic relationship creates something stronger than either was looking for. Henry's father has other plans for his heir's legacy, though, and the danger he poses forces Blanche to take more drastic measures than she ever thought possible. 

Too bad for Blanche's enemies that some things never change. She's willing to do whatever it takes to fight for those she loves. Anyone in the way is guaranteed to get burned.
