I’m not a big mystery novel fan, but once I got into this book (I put it down a few times early on), I liked it and it flew.  The mystery centers around a best selling author and the woman who is writing her biography.  So books and writing play a big role in the story, which is part of what kept me so interested.  Most of the characters are compelling and complex and the twists in the story keep unraveling all the way to the end.  This is fairly light reading–fun and easy.  A secondary storyline about twins and their psychological and physical connection is pretty interesting.  It give the story another layer of substance, though the narrator’s own  obsession with her twin who died at birth gets a bit stale by the end.  Still, a good read, especially on a rainy day.
