The Circle Opens

The Circle Opens is a quartet of novels written by Tamora Pierce and set in a pseudo-medieval/renaissance era. It mainly revolves around four teenage mages, each specializing in a different kind of magic, as they find that they are forced to deal with mages whose powers are similarly unusual to their own. The series consists of the books Magic Steps (2000), Street Magic (2001), Cold Fire (2002), and Shatterglass (2003). The Circle Opens Quartet is the sequel quartet to The Circle Of Magic Quartet, and is followed by "Battle Magic" and The Will of the Empress.

Plot and characters
The students are now 14 years old and fully qualified mages. Briar, Tris and Daja have gone travelling with their teachers, and Sandry has moved in with her great uncle, Duke Vedris, in the Duke's Citadel. They believe they're still too young to teach but the decision is not up to them. Each of the four finds someone, or some ones, with magic, and according to the rules they must become the teacher until a more suitable one can be found. Each of the four also encounters a series of crimes they feel obligated to stop, and they must balance their teaching responsibilities with aiding the law.

Publication and reception
The Circle Opens books began being published the year after the Circle of Magic quartet concluded in 1999, with the four books appearing one a year in 2000, 2001, 2002, and 2003.

The series' publisher, Scholastic Books, published a lesson plan for teachers to use the quartet in the classroom. The lesson plan suggests exploring the series' "refreshingly multiracial world," its representation of the student experience, and literary techniques of sensory writing, simile, and plot suspense.
