Morea: Fury of the Angels (Morea #7)

Everything has gone wrong for Morea Doloniac: her friend and mentor, Knight Terkio, has disappeared, and is presumed dead. Immaros, leader of the Angels, has escaped, taking with him a virus made using Morea’s blood cells. And, as for Torrès, he leads a dissident faction, The Hydras, within the Council of Dragons.

But life goes on. That is precisely the problem when you are immortal, because things are going to get more complicated in time... With the Dragons under the threat of a bacteriological weapon, which could exterminate their whole species, Morea is deprived of her allies and support. The war between the Angels and Dragons seems to have entered a decisive phase.
