This is a darker PNR series with the leader of the highest order of angels, Adrian and his sentinels keeping watch over the "fallen" angels, now vampires. The sentinels have used the lycans as their guards but some of these shifters are looking for an alpha to lead them out of this servitude. Adrian also feels hypocritical since his job was to rip the wings off of the watcher angels when they did the forbidden, and mated with humans. But has been in love with a mortal over the centuries and his punishment is finding her century after century as her soul is reincarnated and he finds and loses his love again and again. This time Shadoe is reborn in Lindsey, but this version has some extra gifts and already a vampire hunter so she comes on the scene when someone is killing sentinels and the vampires are becoming infected with disease. They are thrown into an investigation to determine the source of all the chaos before the fallen leader Syre discovers that his daughter Shadoe has been reincarnated again in Lindsey and finally changes her into a vampire.
This was an action filled read and had a great build up from the beginning and I really did like this book. It had all my favorite elements with a darker storyline and strong H/h characters.
