Kill 6 Billion Demons. Book 5

Sorority sister Allison Ruth has seen it all. Ripped away from her comfortable and mundane life to Throne, the multiversal metropolis at the center of all worlds, she has been unwittingly swept up in an ancient feud between tyrannical god-kings, the host of a power she neither understands nor controls. She has broken into the grand palace of the Blood Flower, plunged the depths of the vault of the grand dragon Mammon, and fought tooth and nail in god-emperor Solomon's inter dimensional martial arts tournament. But now the sky seethes with fire. The most powerful demiurge, Jagganoth, the Wheel Turning King, has returned with his swords unsheathed, and the simmering anger between the rulers of the Red City threatens to boil over into all out war. A war she may not survive.
