I would give it a 3.5 or 3.75, but not quite a 4. I like the characters, but it moved just a little slow. Although, that's not surprising for the 1st book of series since the author needs to set things in place. Still, I am looking forward to the rest of the series! 
 ADDENDUM: 
 Now that I am fully invested in this series and have reread this book a couple of times, I have reevaluated my opinion and feel this is a 5 star series all the way!
