At Death's Door takes a very interesting take on angels, demons, their motivations, and how they all got here. I really enjoyed this look at the world as it took a new turn that I hadn't read before. There is a story about the Garden of Eden that I particularly enjoyed, but can't say much more. Let's just say that it gives the story of Adam and Eve a whole new dimension.
Sara and Daniel's story wasn't always a happy one. Their story was the small bit of romance in the story, and it was a bit of a tragic one - but not completely. Their history was a little confusing and there were a few things I never quite seemed to wrap my head around - but they were little things. Their history set up a ton of great surprises to come out as the story unravels and leaves a lot of questions unanswered - perhaps more will be revealed in book two.
Both characters were quite dynamic. While Sara had the most growth and change due to her circumstances, Daniel has his moments as well, especially towards the end of the story. Sara's son raises a lot of questions for me. I know he is something special, but he just didn't seem quite right to me. I hope the author makes his personality and character more clear in the second book.
