Astonishing X-Men: Children of the Brood (Astonishing X-Men Vol. 3 #38; #40; #42-43, Uncanny X-Men #162)

The fearsome Brood have overtaken the orbital research satellite known as Pandora's Box - stranding Beast's girlfriend, S.W.O.R.D. agent Abigail Brand. Embarking on a daring rescue mission, Beast, Storm, Colossus, Kitty Pryde and Lockheed will encounter old friends and older enemies. But to escape the inescapable Pandora's Box - commissioned to house hazardous experiments on the universe's horrors - they must not only survive one of the most dangerous alien species in existence, but also make an impossible decision: Even if it means sparing untold lives, can the X-Men bring themselves to rescue the Brood along with their friends? Plus: a classic tale of the Brood by Chris Claremont and Dave Cockrum!
