Rock War Bk 2 Boot Camp by Robert Muchamore

Jay, Summer, and Dylan are headed for six weeks of boot camp at uber-glamorous Rock War Manor, where a film crew will follow them day and night as they make friends, work on their music, and party, party, party! As well as all the glitzy premieres and performances at music festivals, the teenage contestants have plenty to deal with in their personal lives too. As the live showdown approaches, Jay, Summer, and Dylan must give everything to lead their bands through to the next round of competition.
