Description of Cecily Herondale:

Cecily is a very beautiful young woman, with gleaming black hair and startling dark blue eyes, traits she shares with her mother, Linette Owens, and brother, Will Herondale. She has pale skin, high cheekbones, and full lips. She is also quite small, contributing to her semblance of defenselessness, and is often assumed to be fragile and delicate, surprising people with her strength because of it.
