This was a great book until the last 25% or so.
Extra points for excellent russian here and there, tho I still can't figure out why stupid typos were left untouched. "Pecherskaya" was spelled "Pe r cherskaya" literally half the time. No matter the language, it's an annoyance. "The band was called "Gryaznykh Angelov"...". Say what? @.@ A minor mistake, sure, but on top of interchangeable peRcherskaya it screamed "I don't really care. they won't get it anyway.", not to mention the name is such a cliche. What else... "'mu'dak' means 'asshole'". Sure if "asshole" means "meany". Let's be nice, I guess. So, that was the minor stuff.
My major complaint - and it's me, probbly, since I like sex in my books in very moderate amounts - is that the last 20% turned into pure porn. I really don't care who topped whom in the end, how many times and how sticky the stickiness got. Both characters, especially Zak, were crazed enough on sex from the very beginning, but by the end the lust came out full force without MCs surfacing for air for 20% straight. I lost all interest in the book and going to DNF it at 93%.
That leaves me with - what? 75% is pure awesomeness, save for the typos. I can easily dish out 5 and more shiny stars. The last 25% tho? A star and a half maybe.
