A Touch of Crimson is a fine specimen of its species. Maybe even better than fine. However, I am sick of unfinished books. It pisses me off beyond belief and makes me pluck one star with a sadistic grin. I cannot respect an an author who is uncapable of making room for a sequel without making you feel like you've been robbed of something. 
 But, my frustration aside, the book works very well until the last few chapters when the problem between the two main characters gets resolved in a rush and a lot shit happens within 20 pages, making one feel confused and cheated out of the complexities which might have arisen. 
 The punchline is, I enjoyed the characters and the story enough to make me care enough to be pissed off. So there. 
 Yeah, ok, sex scenes are good and the chemistry between Adrian and Lindsay is plausible and natural despite their preternatural identities. 
 Worth the while, sure. Still makes me wanna go all vampire on Sylvia Day's ass for forcing me to read the sequel. Bitch, I would've read it even if you finished the first book properly.
