Sworn Soldier Series

When Alex Easton, a retired soldier, receives word that their childhood friend Madeline Usher is dying, they race to the ancestral home of the Ushers in the remote countryside of Ruritania. What they find there is a nightmare of fungal growths and possessed wildlife, surrounding a dark, pulsing lake. Madeline sleepwalks and speaks in strange voices at night, and her brother Roderick is consumed with a mysterious malady of the nerves. Aided by a redoubtable British mycologist and a baffled American doctor, Alex must unravel the secret of the House of Usher before it consumes them all.

After their terrifying ordeal at the Usher manor, Alex Easton feels as if they just survived another war. All they crave is rest, routine, and sunshine, but instead, as a favor to Angus and Miss Potter, they find themself heading to their family hunting lodge, deep in the cold, damp forests of their home country, Gallacia.

Alex Easton does not want to visit America. They particularly do not want to visit an abandoned coal mine in West Virginia with a reputation for being haunted. But when their old friend Dr. Denton summons them to help find his lost cousin—who went missing in that very mine—well, sometimes a sworn soldier has to do what a sworn soldier has to do...
