The Secrets of Signora Cortese
Venice, 1561. Isabella Cortese has taught herself alchemy out of stolen books, and in eleven weeks she has done what the Republic’s own sorcerer has failed to do in fifteen years — grown the philosopher’s stone. When the vessel cracks, the escaping gold begins turning her to metal, starting with her hand. The only glass strong enough to contain it belongs to Aurelio Zorzi, who has the fortune and the craft but not the freedom: the Republic owns his magic and is still waiting on the stone he’s never managed to produce. She has two months before the gold reaches her heart. He has the same two months before the Republic takes everything he has. Neither of them can finish this alone.
