There are scenes of an explicit nature not suitable for younger readers.This is another series by Felicity Heaton that I love!Apollyon is the original angel of death, but he has been guarding the bottomless pit for his master for several centuries. He is very lonely, and passes the time by looking into a special pool of water, watching the people on Earth. When he hears a call from his master, he answers it.Serenity is a mortal, but she is also a witch. When she casts what should be a simple vengeance spell, she it totally unprepared for Apollyon's appearance.I loved both of these characters, and I was slightly disappointed that the book was so short. I felt that it could have been a bit longer. However, I will forgive Felicity, because the story is fantastic (as usual) and has some great moments in it. The coffee scene made me chuckle! Apollyon is the perfect dark angel! The passion between the two characters nearly burns the pages up! I highly recommend this book if you want to get all hot and bothered!
