Though I'm usually a fan of MJD and enjoy her writing I was very disappointed with this book. So disappointed that I didn't even bother to finish it.
In Under Cover the two rather annoying characters meet in an elevator and within moments are desperately trying to jump each others bones. I'm no prude, but c'mon, gimme a break. For what bit I did manage to hang tough with and read the bubble-head blond is jumping to conclusions and running away only to be easily found, and adding insult to my injured reader's soul, needing rescuing by the ultra-cute, unfailingly patient and understanding male from whatever crazy, perilous situation she'd put herself in. That over, within moments the ninny finds another reason to jump to her next erroneous assumption and goes running away AGAIN. I was like "Are you kidding me with this?" Nope, not kidding. Anyway, this schtick got old fast.
So despite arguably hot "love" scenes and an interesting bio-espionage slant, I decided to retreat and go undercover from this book. :-p
