Mia and the Traitor of Nubis by Janelle McCurdy
You can't escape the shadows . . .
The Elite are imprisoned, the Reaper King is once again banished from the world and the city of Nubis is trying to return to normal. So is Mia, but it's not so easy. Coming to terms with new powers and being the tamer of two umbra, she's also plagued by nightmares. Is the fear all in her imagination? Or are the agents of darkness somehow planning another assault? Once again, Mia's skills and resilience will be tested to their limit.
This is the second book in the sensational Umbra Tales series, illustrated by Ana Latese.
