"Headed by the humanoid Bastion, Operation: Zero Tolerance combines man and machine to create a living breed of Sentinels-- 'protecting' humanity by stripping it away! Three generations of Xavier students-- the X-Men, X-Force and Generation X-- fall under cyborg siege, and it's hard to outnumber enemies who could be anybody. New X-Men may not emerge in time to rescue the besieged heroes, so who will? -- dust jacket back.
