From the publisher:

This deluxe hardcover collects Runaways: Parental Guidance and Runaways: Live Fast. In Parental Guidance, the secret super-villain society is back, but this all-new group isn't made up of the Runaways' evil parents. Who are these shadowy players, and what do they want with the Marvel Universe's next generation of heroes? Plus: When the youngest member of the Runaways is separated from her teammates, Molly Hayes must survive a night alone on the mean streets of Los Angeles! The 11-year-old mutant girl soon hooks up with a new group of runaways, but is their mysterious leader a hero or a villain? And in Live Fast, the Runaways say good-bye to the past, and make hard decisions about their future. Plus: Still reeling from the events of Young Avengers/Runaways, the teenage heroes must now confront a horrific enemy who threatens to tear the team apart.
