Character Role Analysis

Cath and Wren

Cain and Abel, Viola and Sebastian, Cath and Wren. Okay, so maybe our heroine and her twin sister aren't quite that dramatic, but they're definitely dramatic enough.

In less than a year, Cath and Wren go from being partners in both life and Simon Snow fanfic to practically being estranged. For the first time in their lives, they go three months without talking—Wren's too busy partying, and Cath's too busy hiding and fretting about Levi. But at the end of the book, when Wren decides she wants to room with Cath their sophomore year, Cath (surprisingly?) says no. It's always a struggle to find yourself, but differentiating yourself from your identical twin makes it that much harder.
