The Bedlam Stacks

Set in the same world as the lovely, quirky The Watchmaker of Filigree Street

This story follows Merrick Tremayne, agent of Britain and the East India Company, who is assigned to travel to South America and acquire cuttings to start a necessary quinine supply outside of the continent's monopoly. But the mission becomes more personal as they pass through territory his father and grandfather travelled. It's a magical historical fantasy with fascinating characters--and at least one familiar old friend. I highly recommend it!
