Résumé: The Thunderbolts' wild ride continues as Thunderbolts Mountain is being used as temporary incarceration for captured superhuman combatants. With so many super-powered people in one place, how can things possibly go wrong? Plus: Songbird. Moonstone. The two longest-serving members of the Thunderbolts, but that's practically all they have in common. Songbird has vowed not to let Moonstone corrupt her team, while Moonstone schemes to kill Songbird in the field. Follow the pair of heroes as they head inexorably toward confrontation - on a collision course that may tear the Thunderbolts apart! And finally, the Thunderbolts work for the American government - but the Radioactive Man and the Swordsman are foreign citizens. When a mission goes against the interests of their home countries, where will their loyalties lie with their team, their homeland...or themselves?
