If you haven't read the other books in this series, STOP, go back and read them. This is a continuing journey.
In the last book, Kobal and River found the reason for the breaking seals. It was her actual father in conjunction with the wraiths breaking them for Lucifer. Her father is now no more, the wraith he had become absorbed into the Fires of Creation.
As this book opens, River, Kobal, Hawk, Corson, Magnus, Bale, several Skelliens and some Hellhounds are making their way to meet up with the other demons who would be fighting with them here in Hell. They reach The River Asharún and Kobal informs them they wouldn't be traveling on it even though it's the quickest way to his chambers and the entrance to the meeting place. River won't hear of it, and insists she can handle being that close to the wraiths for the short time it would take them to reach their destination.
Against his better judgement Kobal gives in and Corson summons the boats. Unfortunately, they are attacked and then they continue on by going through the Oracle. Once there, River is hoping to see her brothers, instead she gets Angela, the angel who appears to be trying to tell her something. It's as they are arguing about whether Angela is good or bad, angel or something else when someone else makes himself known. While in his raven form Caim tells them that Angela isn't an angel and also that the angels are indeed trying to communicate with River. He isn't there because of Lucifer and wants to speak with Kobal.
Whether Caim has been truthful about being on their side remains to be seen, but first things first. They spend the night recharging in Kobal's chambers, then meet up with the others. In spite of all their preparation, Lucifer does manage to get ahold of River. In the process of getting her back we learn a lot more about River and her powers.
This book once again had me enthralled and not wanting to put it down until I was finished. So much happens, with action on almost every page. Plenty of hold your breath moments, some that made me giggle, some that made me cry and let's not forget those sizzling scenes with Kobal and River.
I am looking forward to reading the spin-off of this series Hell on Earth.
