Gilbert Ptolemy — a freed slave turned monster bounty hunter — is sent by the Peregrine Estate to recruit a group of recently emancipated cattle hands, freed in the wake of Granger's Emancipation Enforcement on June 19, 1865. Joined by fellow agent Sarah Lockhart and fame-seeking gunhand Oliver Maine, Gilbert knows the work will be hard — but nothing could prepare him for what they find.

Inside a mission in San Antonio, Sarah and Gilbert discover the depth of human horror — an act of cruelty that demands vengeance. Bound by grief and fury, Gilbert and Sarah set out to hunt down those responsible, their path marked by bloodshed and a love neither of them expected.

San Antonio Mission is a novella brimming with heart and vengeance. The second book in the Peregrine Estate Trilogy, a tale of violence, raw emotion, and the impossible love that blooms in its wake.
