Y: The Last Man Compendium 2

"In 2002, the world changes forever. Every man, every boy, every mammal with a Y chromosome everywhere on Earth suddenly collapses and dies. With the loss of nearly half the planet's population, the gears of society grind to halt, and the world's women are left to pick up the pieces and try to keep civilization from collapsing entirely. The gender extermination, however, is not absolutely complete. For some unknown reason, one young man named Yorick Brown and his pet male monkey, Ampersand, are spared. Overnight, this anonymous twentysomething becomes the most important person on the planet--the key, it is hoped, to unlocking the secret of the mysterious sex-specific plague."--Back cover of Volume 2.
