Obsidian Prey - Jayne Castle
I like Jayne Castle/Krentz's style. Obsidian Prey didn't turn out to be my favourite ever book in the Harmony series, but I enjoyed it.

Not a spoiler but a comment on the writing later in the book.

Towards the end (and I'm not sure if this was the book or me as reader) it seemed the heroine became a tad shrewish (although I hate that word) instead of kick ass but vulnerable.
