Gail Simone announced on her Tumblr that her DC series The Movement would be ending with issue #12. The series was one of two "teen focused" books released by DC in 2013, along with Green Team: Teen Trillionaires, which ended last month. While The Movement had a small fanbase on various Internet sites, the series never gained a large readership. In January 2014, the book had an estimated 6,600 sales, the second lowest of New 52 books (the lowest being the aforementioned Green Team: Teen Trillionaires.)
Simone mentioned that the characters seen in The Movement might appear in another series in the future. With the cancellation and probable reboot of Teen Titans, it wouldn't be surprising to see some of The Movement appear there.
