That was always my favourite subject in school. ;)
I finished reading Lucy Monroe's Deal With This over the weekend. I must say the woman writes some damned fine sex. :D The hero and heroine were nicely flawed, you know what I mean? Each had issues to work through, but not such that they were crippling to either of them, nor were they tedious to me as the reader. I get tired of woe-is-me characters. These most decidedly were not that. Strong but flawed, yeah. Lucy Monroe is very good at finding that balance in these lead characters.
I really dug the secondary characters, too: the housemates and co-workers of the heroine, Jillian; her best friend and bestfriend's family; the hero's (Alan) boss (We don't really meet any of the other people in his life. He's undercover, after all.). They were well fleshed out, multidimensional, fun. In short, I would go out drinking with these people--and that's about the highest compliment I can give fictional people.
The stolen technology plot was cool, too. I wish there'd been more of that along with everything else, but that's my own bias in favor of spy movies and action/adventure coming through. I love that stuff. I suppose, though, that all the hot sex was a fair exchange. ;D
