Secret Invasion hits the U.K., and only Captain Britain and MI:13 stand in the Skrulls' way!

The shape-shifting aliens' mysterious goal in England could turn the tide of battle worldwide, but the emergence of the fabled sword Excalibur — once again locked in stone — may lead to salvation. But who can claim the mythic weapon? Pete Wisdom? Spitfire? John the Skrull? The Black Knight?

It's science fiction vs. fantasy as the war machines of the unstoppable Skrull army invade the magical realm of Avalon. Can Pete Wisdom and the rest of MI:13 keep the Skrulls from taking control of the world's magic? Will this be our heroes finest hour? Or has the sun finally set on the British Isles?

Collecting Captain Britain and MI: 13 #1-4 — written by Paul Cornell (Wisdom) and illustrated by Leonard Kirk (Agents of Atlas) — plus a classic Captain Britain tale from Marvel Team-Up #65-66 (1978) by Chris Claremont and John Byrne.
