This is sweet and unexpected Gay-For-You or Out-For-You (depending on your opinion on Kinsey and stuff) from Voinov. The hot and a bit kinky sex was not unexpected, though. 
 For those who read and liked Special Forces, it will be a nice dip into some tiny SF world (Vadim and his family, though there is no Dan). The hero (Nikolai) is Vadim's son, all grown up, and man making his way in the world and trying to live by his (high) principles. He is gentle and caring, loyal and just plain adorable. He couldn't be more different than his family (After all, Vadim was a real BAD guy, his ex-wife is not sweet at all and his daughter is cold, vindictive woman). 
 Nikolai's love interest, Henri, is a sexy thirty something heir of a mining empire. I have to admit, he was funny and all, but he felt unreal. I found his behaviour strange and completely ... unbelievable. But maybe I'm just a cynic. 
 The best part of the book was seeing Vadim and Nikolai interact together, the father-son bond. I read the book in one go because in spite of Henri's character who was a bit off, the romantic plot is supported by good business war sub-plot AND the author's style was really fluid and beautiful.
