Y: The Last Man, Vol. 4 Safeword

WINNER OF THREE EISNER AWARDS!
After a devastating plague, Yorrick Brown is the last man left alive in a world of women. On the run from Amazon extremists who would be happy to see him dead, his friends leave him in the care of Agent 711. But 711 is not the tragic woman she seems to be and Yorrick is propelled into a drug-fuelled nightmare of blood and sadism. Collects issues #18-23 of the runaway hit Vertigo series by Brian K. Vaughan (EX-MACHINA, RUNAWAYS) and Pia Guerra.
