Uncanny X-Men #4

"• Mutantkind is teetering on the brink of extinction once more! While some mutants seek refuge, others are eager to fight for their species' survival. • And in the case of the UNCANNY X-MEN, that means taking the fight to those who would hasten mutantkind's decline! • But are the X-Men biting off more than they can chew when they try to hunt down the DARK RIDERS on their own turf? Rated T+ "
