Dark Blood Awakens - Mwindajis, #1

Dark Blood Awakens is a paranormal urban fantasy incorporating Black girl magic with myths from the African diaspora. As a child, Makeda's mom forced her to abandon sorcery. Instead, she pursued a career in nursing while killing monsters with her family of mwindaji. For over a millennium, the mwindaji have hunted Korlemo, a 1000-year-old vampire. While working in Haiti, Makeda's desire to recapture her sorcery skills increases.
When a lead takes her to a Kentucky rural hospital searching for Korlemo, she uses Baoumali, the language of sorceresses, to reclaim her heritage. During her investigation, Makeda develops a steamy romance with the local sheriff and uncovers a macabre secret the hospital administration will kill to keep silent. With time running out, Makeda must recapture her sorcery and choose where her alliances lie.
If the mwindaji cannot destroy the monsters haunting the hospital, people will die-starting with her boyfriend.
