Tutu by BL Maxwell

Kit Nelson was thrown into the world of demons and cults as a child. He’s learned to depend on no one, and to do all he can to keep himself safe from dark forces. He also knows he can’t trust anyone else with his life. He knows what the demons who hunt him have in mind for him, and he’ll fight it every step of the way.
Tommy Smythe and his sister Lola have been fighting what they know is a rising tide of evil for years. They’re prepared with all their paranormal weaponry, including the assistance of an ancient god who has fought demons his whole existence. Tutu, the Egyptian god and Master of Demons has chosen Tommy to be his vessel and his sword when needed to destroy any and all demons.
A new threat ripples through the dark underworld, one that will be felt across all mankind. A demon has chosen one whose body he will use to return to the land of the living. But only if Kit, Tommy, and Lola can’t stop him. Only Tutu has the power and knowledge to protect them from the demon Rerek, and he also knows even with his help, this is not going to be an easy battle.
