This book is just AMAZING! I love everything! combination of romance and mystery. Oh by the way.. it's a tear-jerker too. 
 It's about Ivy and Tristan, they were so deeply in love. An accident changed everything. Tristan died in the accident leaving Ivy hurting and depressed, that she lost her faith in Angels.. Tristan became an angel and met Lacey Lovitt, another angel that taught him how to communicate Ivy and try to make her believe in angels. 
 Tristan found out that their accident wasn't really an accident. Someone set them up. Ivy and Tristan's mission is to find out who caused their accident. 
 A Must read :) I can't wait for Evercrossed.
