UNCANNY X-MEN #37

SOMBER STEEL VS. ADAMANTIUM! KILLER VS. KILLER! After the shocking events of WILD RIDE, some of the UNCANNY X-MEN take a much-needed break to recover and lick their wounds, leaving the WOLVERINE to stand watch over them in their vulnerable state! But the Hag, SARAH GAUNT, has a bone to pick with the survivors (an ADAMANTIUM bone), and will just one X-Man be ENOUGH to stop her bloodthirst for revenge? Our most brutal story yet, CLAW VS. CLAW!
