KATIE AT 22: Katie Rose Fowler, the title character of two books that chronicled her very unusual life from age eight to 18, in which she was a kidnap victim at 15 and solved a celebrated local murder case at 18, finally speaks in her own voice in book. In her story we get inside Katie's self-reflective brain as she pursues her post-graduate degrees and her summer job in a criminal defense lawyer's office. Her quiet summer respite's downfall comes when she gets way too involved in a hunt for a serial killer only to become a target for murder herself, surviving two attacks, barely. Young Katie finds she still has a lot to learn about herself. But we learn a lot about Katie from her good-humored and breezy narrative of her adventures pursuing her prey - and about relationships with her friends and lovers in Montana Bahia. (Third book in a series of seven.)
