I am looking for a dark romance I read in 2013-2019. The beginning of the book started with women going to a fight club where you needed a password in order to enter. while there she sees one of the club owners who fights the winner of the night I think. He also has a past where he was trained as an assassin as a child and had to kill his brother. The woman has a daughter who has some kind of illness and dies in the book. Throughout the book, the man has flashbacks to his time as a child assassin in Russia, and one of the times I think he hits the woman's daughter and the daughter stops breathing. I thought with all these details I would be able to find it on google but nope.
