Query: Taking Faith on a Roller Coaster Ride

Wow! If you like roller coasters, try the mystical version. It's all right here in this book. How would we really react if a "Messiah" appeared tomorrow? Watching the characters react was a great opportunity to study my own reactions. Incredulity fades into hope. Doubt inches in to be replaced by despair and renewed faith. Wow! A very, very impressive first novel. It echoes in the mind long after the last page is turned. Thanks, Glenn.
