Golden Scarab. Book 2 of The Windflowers Trilogy.
A year has passed since Kalli escaped from the Ferrasium, but the High Priest’s stranglehold is tightening and his tentacles are extending. As Pharaoh’s royal barges sail toward Wasset the High Priest is poised like an arachnid in his nest, waiting to hatch his plans. Kalli must unlock the secrets of the Golden Scarab before all of Keymett falls under his dominion, but who can she trust?
