"Spark" by John Twelve Hawks -- Gripping and Strange!

Spark, by John Twelve Hawks is about a Jacob Underwood who suffers from Cotard's Syndrome - an actual condition that makes you believe you are dead even though you aren't.   He is a hired assassin who does his job very well since he has no feelings or concept of right or wrong.  Things do change though, and when that happens, this good book becomes great!  The good writing made me want to keep turning pages which led to a very good ending!
