Secrets and half-truths. These litter Renia Baranczka's past, but the city of Paris had offered an escape and 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 buffered the guilt that kept her up at night, dwelling on the endless replays of what happened to her sister.

All too suddenly, the City of Light seems more sinister when 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 a menacing underworld of black market mobsters, navigating threats and fending off abuse to protect the safe peaceful life she's worked so hard for in Paris. Desperate to outwit her enemies, Renia maneuvers carefully, knows one wrong move will destroy not only the plant, but the lives of her and her sister.
