Sadie Hoffmiller has always liked things to be just so. A place for everything and everything in its place. Order over chaos. And of all things Sadie should be able to control, her own wedding is at the top of the list.

With the big day just three weeks away, Sadie is busily adding the perfect final touches to her wedding plans, but the arrival of a mysterious letter that from San Francisco changes everything. The only person Sadie knows in San Francisco is her older sister, Wendy, whom she hasn't seen or heard from since their mother's funeral nearly fifteen years ago.

Sadie has faced off against murderers and criminals in recent years, yet the possibility or reconnecting with her sister is both overwhelming and frightening. Sadie soon discovers, however, that the letter is just the beginning when Wendy's world turns out to be a place of unanswered questions, twisted truths, and more than one motive for murder.
The more Sadie digs into her sister's past, the more she places her own future at risk.
