As the superhuman Civil War threatens to crush the Runaways, the Young Avengers offer assistance - but how can the Runaways trust that they're on the same side? As the Runaways make hard decisions about their future, they confront a horrific enemy who threatens to tear the team apart! Then, the Skrulls launch their Secret Invasion - and the Runaways and Young Avengers both have a Skrull on their team. Coincidence? With Xavin having betrayed his teammates, and Hulkling out of commission, can the Runaways and Young Avengers survive?
