Quintessence Sky

Quintessence Sky continues the story of Horizon, the island perched on the edge of the flat Earth, that began with Quintessence (Tor Books, 2013). A strange fire burns in the sky, altering the balance of the elements and threatening all life on Horizon Island. Matthew Marcheford experiments to determine the cause, while the growing animosity of the manticores and the arrival of more ships from Europe jeopardize the colony's fragile peace. When Matthew's fiancee, Catherine Parris, is betrayed and abandoned deep underground, the secrets she uncovers there may be Horizon's last hope.
