In the catacombs of an ancient ruined monastery, a place hidden away in the Eildon Hills, a legendary land of myth, of mystery, and of magic—the place where he’d found sanctuary as a lad. The network of caves lead him to a steep, decaying staircase, where he discovers a journal, apparently written by Gaelan’s old friend Sir Arthur Conan Doyle, describing his journey to the Otherworld, a land of fairy castles and magical, turquoise rivers and filigree trees hung with Spanish moss. Falling from the journal’s pages a small piece of glass, which Gaelan recognizes as a piece long missing from a stained glass panel he’d created a century earlier. When the opalescent glass piece seems to come alive in Gaelan’s hand, he is suddenly thrust into world far from the fantastical dreamscape Conan Doyle has described.

Gaelan doubts his sanity, wondering whether he is caught in an elaborate, surreal nightmare. Is it possible he has traversed a portal into the future? But how? And why?

The Alchemy of Glass weaves a tale magical as spun glass and terrifying as a shattered mirror, drawing upon cutting edge science and the most ancient of Celtic mythology, intertwining the magic of fairy lore and the harsh reality of difficult choices, returning us to the world of immortal apothecary Gaelan Erceldoune, as his past, present and future collide, in an attempt to prevent a catastrophic future.
