Seventh

Hynd Perrent leads a lonely life, rejected by most of society after a debilitating illness permanently changed him. He has spent nearly a decade investigating the disappearance of a military unit, Seventh Dragoons, in a war nearly a century prior, content to immerse himself in the frustrating search and the book he intends to write about it. When his sister sets him up with a handsome stranger, Hynd can scarcely believe his luck, unable to recall the last time somebody wanted to be near him and did not fear or revile him for his illness.
But Julius Ocere has come for a different reason: Hynd's. He wants to learn what happened to the Seventh and prove that his great-grandfather was not a traitor. While a research assistant isn't what Hynd had hoped for, he takes Julius on. The mystery they uncover is larger than either of them could have imagined, and it will take both of them together to finally put the ghosts of the Seventh to rest.
