In this New York Times bestseller, Tyrese Gibson, multiplatinum R&B singer and movie star, and Rev Run of Run-DMC and star of Run’s House, present a bold, honest, and uncensored look into the male mind.

Tyrese and Rev are the unlikeliest of best friends—Rev is married with six kids, and Tyrese is a single dad still hesitant to settle down. But after an unexpected argument in which Rev insisted that marriage is forever, and Tyrese countered that you could bail when the sex went bad, the two decided not just to agree to disagree but to team up and open their debate to a larger audience.

Manology will help you weed out the cheaters, manipulators, and pimps from the good men, and it will give you the tools to know if your man is the marrying kind. In “Manology after Dark,” the guys even give the lowdown on what men need in bed, before and after they put a ring on your finger. Some behavior can’t be changed, but as Tyrese and Rev share, it’s better to face the truth. With Rev’s hard-earned knowledge on how to make a marriage work, and Tyrese’s sometimes uncomfortable but always honest take on the single man’s mind-set, Manology is your one source to help you take control of your love life and truly understand your man.
