This book is really to me is 2 stories in one. You have the Angel and Warrior Emily and Matt. The other side of the story is Liz and Daniel humans on earth.
I personally loved the story of Liz and Daniel more than Emily and Matt.
When the story takes place as Emily and Matt it has a religious feel to it. The Saints guide Emily and Matt into their jobs on earth.
For a person that is not religious sometimes the Emily/Matt parts were hard to get through. It was not over powering religious though.
I did enjoy the book, I read it in one day.
I do have to say as much as a good read this was, if the story was just about Liz and Daniel I would of probably enjoyed it more.
