I haven't read any of her Stephanie Plum novels but I have read this series. 'Full Tilt' was the first, then 'Full Speed' and then finally 'Full Blast'.
I was addicted to them and I am hoping that there will be a fourth. I would say this one has the most tension and a surprising twist. I won't ruin it, but it's about a person going around killing people, females. It's a murder mystery but still also has the chemistry and relationship between Max and Jamie. In this book, it has progressed obviously since the first and second and is still funny.
I recommend this book to anyone. It is has the "sexy" genre in it, like all good chick lits, but also has tension and murder in it still. I recommend this to those who like chick lits, but this really is a good series. I can't wait to read the Stephanie Plum novels as they're apparently even better. Oh, I suggest, you read the first two novels before reading this one or you'll be confused.
