Mercy by Rebecca Lim

... Mercy wakes on a school bus bound for Paradise...  Mercy is an angel exiled from heaven and doomed to return repeatedly to Earth.  Mercy is never sure whose life and body she will share each time.  And her mind is filled with the desperate pleas of her beloved Luc, who can only approach her in her dreams...

 Mercy has woken up in the body of a girl called Carmen.  Carmen is not dead.  Mercy had just taken over her body.  Usually it is because that person has a problem that Mercy needs to help her with.  But this doesn't seem the case this time. 

I liked this book, but found it a little confusing. I wanted to know more about the background of why Mercy had been exiled, was she the only angel exiled, what does she have to do to get back to Luc, who is Uri, how does she have to 'change', what will happen when she changes...  I know that it's part of the suspense to have all these questions and that they will be answered in the upcoming books, I just felt that I needed to understand why Mercy was put into all these situations.  In saying that I really enjoyed reading Mercy and am looking forward to the next in the series Exile
