Dark Horse, by Tami Hoag

Lost Reference: This book is found in Jack's book shelf in his office while he is speaking with his father in A Tale of Two Cities.

Dark Horse is a fairly straightforward procederal mystery. A young woman is kidnapped, and another is murdered, at a horse racing track. Along comes an ex-cop with a bitter past to infiltrate the horse world and find out who the villain/villains may be. The novel was fairly well written and an enjoyable mystery.

It may relate to Lost in the sense that like many Lost characters, the main character of this novel has a haunting past - and is looking for some kind of redemption and a reason to continue. Redemption of character is a major theme in Lost as many of the show's characters struggle with their past "sins" while trying to solve the mystery as to why they are on the island.
