I'm not sure if this is 4.5 or 5 stars. I'm waffling. It was really AWESOME though. 
 INITIAL THOUGHTS: Ok, I've read plenty of YA angels books in the last couple of years, but this one has to be the absolute most creative and unique take on an angel story that I've read, yet. The female lead, Riley Carver is fabulous. She's feisty, funny, smart and speaks her mind. I loved how she was so blatantly truthful, never telling even a single white lie. This is an angel book, its also a paranormal romance of sorts too. Plus, somehow the author even manages to squeeze in a time travel element. Writing style is straightforward, plot lines are incredible imaginative. The angel mythology in this story was well thought out, engrossing, I loved reading about Guardian angels, Thralls, The Circle of Nine and even Charoum (a fallen angel). The supporting characters: Gabe McClure Pastor Warren and Lacy were all special. What's even more curious is there was a unique sort of love triangle, but this is one I could really appreciate. The ending gave closure to the story, however, I do feel like there may be a lot more story to tell. I hope A. Kress plans to write more books about these characters because I still have questions left unanswered. Overall, I thought this was an impressive new take on a YA paranormal angel story, with just the perfect touch of extra special innocent romance: i.e. first kisses, first dates etc. I would recommend it to both guys and gals alike as Gabe is a very masculine character who even builds and rides a motorcycle.
