A secret city buried a mile under America is discovered through the leakage of Von Doom radiation—a type of energy emitted only by time-travel devices. The Secret Avengers hea underground to a weird metropolis forgotten for decades, because a time machine in the wrong hands is the worst kind of WMD imaginable. Then: MI:13 learns that people are being abducted from villages in the former Yugoslavia—but the British government refuses to act on it. Even the added strength of War Machine and Valkyrie cannot prepare the Secret Avengers for the next level in bioterror. Plus: a can of matter the size of a football, mined from a broken universe, would be enough to turn the Earth into a sun. There are people who would do that either to hold the planet ransome—or just to die knowing they took everyone else with them. And right now there are just three people—Steve Rogers, The Black Widow and Shang-Chi—between us and total annihilation, trapped on a space station in the No-Zone.
