Signed copy of Eidolons by Harrison Fountain (that's me!)
"When TK dies in a car accident, the Grim Reaper offers him a second chance at life, but he says it's more fun as a ghost. As he haunts his small Iowa town, his sleek shell of sarcasm cracks to a terrified lonely inner self. Find out why he'd rather be dead."
I really must thank my parents. Harrison Fountain is the ultimate writing name.
