Erin E. Adams’ 2022 Jackal: A Novel is a stand-alone supernatural mystery novel.
Having successfully escaped Johnstown, Pennsylvania (most famous for a May 31, 1889, flood and a 1923 ethnic cleansing) for a career as a doctor, Haitian-American Liz Rocher is very reluctantly returning to Johnstown to attend the wedding of her best friend Melissa “Mel” Parker.
Very white Mel is marrying her very not-white long-time boyfriend Garrett Washington. As one might expect in a town with Johnstown’s history, many people (including the bride’s family) are not pleased by the marriage. However, the event itself goes off as well as one could hope.
Liz takes her eyes off Mel and Garrett’s daughter Caroline. Only briefly, but long enough for the little girl to vanish.
