Ekaterina Kitarin

Ekaterina (Katrina) Kitarin is a sub-protagonist of the Evanescent series. She has light brown hair and green eyes. She hates any form of evil, and she cares for Layla and her friends as if they were her little sisters. She has a special form of rivalry with her sister, Jadelyn Roselia Kitarin, who is one of the main antagonists of the series.

Evanescent
The quote that inspired the title of the book was said by Katrina. "Life is like that; things leave, disappear, like vapor. It's all evanescent, like my mom said. And eventually proved."

Katrina was the secondary focus of the first book, other than Layla and Aden's parents, since she was originally the primary target of the Jade Rose.
