Secret of the Godforsaken - Accidental Sorcerers, #8

After the Great Storm, Sura, Bailar, and Mik have two years of peace. As senior apprentices, they are now becoming true warrior-mages, the first in centuries. They still enjoy the favor of the folk, but time emboldens some of the opposing factions within House Chelor. After an assassination attempt, a trade mission to the Eastern city of Pyrlast provides a convenient pretext to leave the city for a while.
When their air-ship goes down in The Godforsaken, Termag's greatest desert, Bailar stumbles across a clue to a great secret. But uncovering the secret of The Godforsaken is not as important as escaping with their lives.
