Secrets and half-truths litter Renia Baranczka's past, but the city of Paris had offered the refuge of her dream job. The specialty plant shop kept her busy, but also had brought her to a new friend, Alain. His presence had buffered the guilt of what happened to her sister but, all too suddenly, Alain turns up dead. His demise threatens every secret Renia holds dear, including the rare plant hidden in the shop's tiny nook. It emits a special fragrance that can erase a person's memory - and perhaps much more than that. As Renia races to figure out the extent of the plant's powers, she's confronted by figures from her past who offer a proposal she can't outright refuse. Bit by bit, she descends into an underworld of black market mobsters, navigating threats and fending off abuse to protect the peaceful life she's worked so hard for in Paris. Desperate to outwit her enemies, Renia maneuvers carefully, knowing one wrong move will destroy not only the plant, but the lives of her and her sister.
