   Summary

   When a pre-colonial magical codex resurfaces beneath the Yucatán Peninsula, Hermione Granger expects bad translations, illegal excavation, and the usual amount of Ministry nonsense.

   She does not expect Narcissa Black.

   Drawn into the same cursed ruin by a private expedition, Hermione and Narcissa uncover something far older and uglier than a single artefact: a bloodline curse rooted in the Black family’s burned branches, severed names, and generations of ritual denial. The family tree was never just a record. It was a weapon.
