Daddy's Girl by Lisa Scottoline
I've listened to several Scottoline books now, and really enjoy her pace and style of mystery featuring interesting female protagonists. This time, Natalie Greco, erstwhile law professor, daddy's girl and girlfriend to the "eh" Hank, finds herself drawn to a fellow professor. But when a routine visit to a jail for a class turns into a riot, a murder, and a cryptic message given to Natalie by a dying man, things have definitely taken a turn for the weird...and the deadly.
This is a great cat-and-mouse game, full of intrigue, action, and a great lead character that women will sympathize with and root for. The twist at the end was out of the blue for me, but I found the entire story compelling and interesting. I really like Scottoline - you should too!
Note: I listened to the audio edition, narrated by the unparalleled Barbara Rosenblat. Her voice is fantastic, and she narrates all Scottoline's books - as she should. This is a great listen!
