Query: Great potential but no follow-through

This book makes one of the classic mistakes - instead of showing the reader about the characters through their actions, the author tells the reader. That was one of the distracting things about this book - the dialogue didn't match the actions. So, we have a genius vampire heroine who spends more time thinking about what she's going to wear to a meeting than what's going on in the mission to which she's been assigned. She's an ex-ninja that never does a single martial arts move. Instead, she continually resorts to brute strength. I, like a previous reviewer, was frustrated with her interaction with her love interest. She keeps telling him she has to be equal in the relationship but she never acts like one - again telling instead of showing. She jeopardizes her own mission in order to help out his, not even knowing what his goal was.On the plus side, it is an interesting concept and does show promise...if the heroine ever starts using that genius IQ.
