There are three truths Lark knows with absolute certainty:

- There is nothing she won't do for those she loves,

- Those born without magic will always be seen exclusively as prey,

- Never trust the Zodiac Kinship

When her father falls deathly ill, Lark is sent into one of the most dangerous places in Meridian to save his life. She braves old myths and older magic, but a twist of fate puts a target on her back and the Crowned Assassin of the Zodiac Kinship on her trail.

She can't escape him... but it's possible he can't escape her either.

An unlikely alliance is formed, but when the one thing that matters to Lark is ripped away from her in the ultimate betrayal, she'll stop at nothing to take her revenge. Even if it rips out what's left of her heart.
