This book picks up right where it left off. Beth and Xavier are happy to be together, Ivy is still learning the ropes of human life, and Gabriel is still cool and collected. Life is pretty good for the angels, but happiness rarely lasts forever. Not long into the book, Beth is captured by Jake, a fallen angel, and taken to Hell aka Hades. Jake admits to wanting Beth from afar, that she makes him feel something more. Beth does not take kindly to this, she responds by fighting the whole way. She also meets quite a few interesting characters, from a woman who sold her soul to save a friend to a previously selfish girl who gives up her chance at freedom to save Beth from the literal Hounds of Hell. 
 Beth gets in plenty of trouble in Hades, one would imagine an angel wouldn't be well-behaved in that place. Jake actually saves her multiple times, her friends try to keep her out of trouble and provide her with some comfort. Beth's good intentions get her into trouble in Hades, one time too many. They say the road to Hell is paved with good intentions...how true that saying is in this book. 
 Beth is a fun character to read about. She is very...pure, the author portrays her as wanting the best for others. She is determined, sometimes foolish, serene, and strong. The reader does not see too much of Xavier in this novel, but Xavier still very obviously loves Beth. He is just as handsome and caring as ever. Gabriel is still the cool one of the bunch, taking everything as it comes. Ivy is slightly more excitable, she'd do anything to save Beth. Jake is the evil angel with the handsome exterior, he is charismatic and too suave for his own good. The reader will enjoy getting re-acquainted with these characters and getting to know the secondary characters better. 
 This book was fast-paced, interesting, and fun to read. The author writes very smoothly and the transitions are far from choppy. This book is recommended to young adults/teens-especially those who enjoyed Halo.
