Amelia has unknowingly had a guardian angel watch over her since birth, usually watching from heaven Marcus has been sent to watch over her more closely and moves into the next door apartment to her. Marcus is an angel who believes in following his orders and in his duty but when heaven asks him to seduce Amelia and use her feelings to gain her trust Marcus starts to question the mission he has been given. With Amelia in danger from some demons out to attack her Marcus needs answers as to why someone or something would want to hurt the woman he is falling for. Marcus seeks out some of his angel friends for help to find these answers and to protect Amelia, but sometimes the answers we find are not the ones we want to hear !! 
 For me this series has gotten stronger and stronger with each book, Amazon does say that these can be read as stand alone books but you get so much more by reading them in order. I love the way the author brings back the characters from other books and also introduces you to new ones without it feeling to full of character and a who's who. It was great to visit Apollyon, Lucas, Einar and there ladies again and to have them all working together was great. 
 This book had everything for me, a hot leading man, strong leading lady, HOT bedroom scenes, plot twists, action and adventure and so much more !!!
