Ashley Bell 
 is my first ever Dean Koontz book, and I really enjoyed it. Won't be my last. 
 Creepy, tense, mysterious, and interesting- at 656 pages (that's how long my copy was), it's quite a long book but it doesn't feel long, if you know what I mean, which is a testament to its merits. 
 I've seen some reviews saying they didn't like the ending but I completely disagree with this. Very enjoyable. 
 Bibi Blair is a 22 year old writer, surfer, daughter, friend and fiance. After some strange symptoms, she goes to the hospital to discover that she is in the advanced stages of an incurable brain cancer. The next day, her cancer is gone. After a visit from a psychic, she discovers she was saved in order to save someone else - a girl called Ashley Bell. But she wasn't supposed to know this and now bad people - or possibly something more - are after her, and they'll kill her to stop her finding Ashley.
