The Reanimator's Soul - The Reanimator Mysteries, #2

An autistic necromancer, his undead lover, and the case that could destroy everything. When a necromancer turns up dead, Oliver and Felipe think it will be the perfect, straightforward case for their new partnership. That is, until it leads them to a clinic promising a cure for magic, but they aren't the only ones investigating the Institute for the Betterment of the Soul. Oliver's ex, Ansley, is in town, and he's certain the clinic isn't the paragon of righteousness it claims to be.
Forced to help Ansley infiltrate the institute, Oliver fears he is out of his depth in his work and in love as old wounds and bad habits resurface. But Oliver isn't the only one struggling. Pulled between his cases, Oliver, and his daughter returning home for the summer, Felipe is drowning. Just when he thinks he finally has everything under control, a new reminder of his untimely demise threatens to throw his life into a tailspin once more.
Between festering wounds and secrets, Oliver and Felipe's lives stand upon a knife's edge. To face the evil lurking behind the clinic's genteel smiles, they must stand together or face the destruction of the place they call home.
