Considering this is the first book in new series it's not bad. The characters are interesting enough. I would have enjoyed a faster pace with much more back story on the reapers. When they first introduced sebastian's character I found him to be of interest and was disappointed the writer had not given something more to tempt us. Reading the synopsis of the next book, hexbound, I am thrilled that they will give him a more up front character introduction for the sequel as well as possibly future titles in this series. 
 I do think this would have made a better adult series rather than teen. You can see the author skating around the violence , or rather lack thereof, issue amoung other things. I am not trying to encourage such things but, when your dealing with big baddies that want to suck a person's essence / energy / soul the fight would be less cordial than portrayed. Still enjoyed this book & would recommend is as a "for fun" read.
