Title page verso series statement: Before she disappeared 3. Author's website states this book is a standalone.

A recovering alcoholic with more regrets than belongings, Frankie Elkin has devoted her life to doing what no one else will--searching for the lost and forgotten. When the police have moved on, when the public no longer remembers, when the media has never paid attention, Frankie starts looking. A new case brings her to Mattapan, a Boston neighborhood with a rough reputation. She is searching for Angelique Badeau, a Haitian teenager who vanished from her high school months earlier. Resistance from the Boston PD and the victim's wary family tells Frankie she's on her own--and she soon learns she's asking questions someone doesn't want answered. But Frankie will risk it all to discover the truth, even if it means the next person to go missing could be her. -- from book jacket.
