Gemi's sister is missing.

Ashlyn left on a business trip two weeks ago. Gemi hasn't heard a word from her since the day she was supposed to come home. Not a phone call, not an email, not a single-emoji text. Desperate, tired of all the secrets Ash has been feeding her, and terrified something horrible has happened, Gemi searches Ashlyn's bedroom.

Hidden in Ash's closet, Gemi finds a calendar filled with mysterious appointments. Most intriguing are two unfamiliar . . . words? Places? Names? One appears every week going back more than a year. It's not much, but Gemi has a lead.

She should ask for help. She knows that. Going rogue will be much faster than waiting for the cops, though. But when she finds herself surrounded by yakuza crime bosses, Gemi fears she may be in over her head.
