Mia And The Traitor of Nubis by Janelle McCurdy

Mia grapples with the responsibility of her new powers and uncovers even more of Nubis’s secrets in this thrilling second book in the Umbra Tales middle grade series that’s Keeper of the Lost Cities meets The Golden Compass.

The Reaper King’s attempt to break free and thrust the rest of the Kingdom of Lunis into darkness has been thwarted, but all is still not well in Nubis, Mia’s moonlit kingdom home. The whole city is on guard for another attempt to resurrect the Reaper King. Though imprisoned, his followers, the Elite, are still inside the city, and tensions among the population are at an all-time high.

Meanwhile, Mia struggles to cope with her new Lightcaster powers and to fit in with the rest of the tamers, many of whom are skeptical of her abilities. But it’s the appearance of old friends and new maybe-enemies that will truly put Mia’s abilities—and the loyalties of everyone she trusts—to the test.
