Don't be put off by the dreadful cover of this book, it is a good read. Wicked Charms is the third in the series featuring Diesel and Lizzy. The first two were written by Evanovich and this one has a co-author. I hadn't heard of Sutton before but the jacket mentions that he has written and produced for tv – Cheers, Boston Legal etc.
I'm never sure about co-authored books but this one has been done well.
The book is a comedy crime caper – there is magic, superpowers and a little non graphic sex – but don't let that put you off. It is basically a hilarious escapade.
Of course, I may be biased since I have read all of Janet Evanovich's books as soon as I can get my hands on them. (Don't confuse her with Stephanie Evanovich – I originally though that name was chosen to hook up with true Evanovich fans but have now been advised that she is Janet's niece!)
