From Ash and Darkness

After banishing the evil djinn, Bax's life has returned to normal—almost. His guilt-fueled nightmares won't relent until he musters the courage to return Ifrit's artifact and finally lay the demon to rest. But nothing in the djinn-verse is ever easy. Someone has summoned Ifrit back into the world, placing Bax at the center of the swirling dark wishes the djinn is fulfilling for his new master. As Ifrit's attacks grow deadlier, Bax and his friends must uncover the identity of Ifrit's new master and convince them to banish the evil spirit. But with no high-powered lunar eclipse for another one hundred and fifty years, banishment might be impossible.
