Eleven long books before this one and now the flow in the twelfth part show that Nalini Singh still has a lot in stock. The author has brought a bigger evil for Elena and Archangel Raphael. The two have fought evil together with full might and so far they have won the war on all occasions. The effort to turn Elena into a vessel has also failed and after that Elena and Raphael are not the same rather they have changed in a big way.
There is no time for them to look at all those things because a strange fog has returned to the world and it is engulfing everything very quickly. It is the territory of Archangel Lijuan where the fog has appeared and no it is moving forward. The evil is so big that the Archangel might not be able to stop all of this and they might perish in front of it.
If this continues then the world will go down in chaos once more. Justine Eyre narrates how everyone becomes concerned about the situation and more concerned than anyone else is Elena because she has to stop it at all costs. Angels’ Blood and Slave to Sensation are great books without any doubt but there is nothing like this book which takes action to a different height.
The archangels fall in this war and the evil which has awoken is centuries old. If the evil spreads then there is a threat that it will take down the entire world within no time. The source of the evil is still unknown and the agenda is vague too. The heroes can only make assumptions this time because they are not prepared.
