In More Genie Problems, the third novel about Marvin Harper and his genie Fatima, Marvin has more problems of every kind.
Shrill feminist Michelle LeClerc has been an occasional annoyance to Marvin in Three More Wishes and One More Genie; now Michelle steps up her game. She makes a demon-pact with pink-haired succubus Fanzelle, and Marvin Harper is targeted by the pact.
Succubus Fanzelle uses her authority under the pact to make the “hero billionaire” be no longer a billionaire, and she does her damnedest (pun intended) to make Marvin be no longer a hero. Fanzelle makes Marvin be five-foot-two and puny-muscled again, and there is nothing that Fatima can do to reverse this.
In the process of making Marvin be both un-billionaire and un-hero, Fanzelle kills and damns a character who has appeared in both of the first two books.
But the ambitions of Fanzelle the succubus run beyond ruining Marvin’s life and collecting Michelle’s soul. Fanzelle is using the demon-pact as a springboard to cause a second war between Heaven and Hell. If Hell wins, Earth will become a literal Hell for humans; if Heaven wins, Judgment day will immediately follow. Either way, humans have a problem, and only Marvin and his genies know about the problem.
Marvin can command two other genies besides Fatima, but those other genies are not much help. Roshradzam, the Genie of the Ring, wants to help Marvin—but he is from Brown Tribe, so he is a magical weakling. Sumera has a rotten attitude, even for someone from Blue Tribe, so she gives Marvin headaches.
Speaking of giving Marvin headaches, Elvira learns something unflattering to Marvin at the beginning of More Genie Problems; Elvira goes back to acting the bitch.
