Cipher in Glass

A single misplaced vase could ignite a slaughter. Khalil, a master glassblower in thirteenth-century Tabriz, has spent years encoding rebel communications within the luminous layers of his art—until his most dangerous creation is seized as a diplomatic offering bound for a Mongol commander's tent. Now he must infiltrate a sprawling encampment of warriors and imperial scholars to retrieve the vessel before its hidden message is decoded. Every shard of beauty he crafted has become a weapon turned against his people.
