Before, Scopuli. It has been centuries since Thelia made the mistake that cost her the woman she loved--Proserpina, the goddess of spring. As the handmaidens charged with protecting Proserpina when she was kidnapped, Thelia and her sisters are banished to the island of Scopuli and cursed to live as sirens--winged half-woman, half-bird creatures. In luring sailors to their deaths with an irresistible song, the sisters hope to gain favor from the gods who could free them. But then ships stop coming, and Thelia fears a fate worse than the Underworld. Just as time begins to run out, a voice emerges, Proserpina's voice, and what she asks of Thelia will spark a dangerous quest for their freedom.

Now, Roanoke. Thelia can't bear to reflect on her last moments in Scopuli. After weeks drifting at sea alone, Thelia's renewed human body--a result of her last devastating sacrifice on Scopuli--is close to death. Luckily, an unfamiliar island appears on the horizon: Roanoke. Posing as a princess arriving on a sailboat filled with riches, Thelia infiltrates the small English colony. It doesn't take long for her to realize that this place is dangerous, especially for women. As she grows closer to a beautiful settler who mysteriously resembles her former love, Thelia formulates a plan to save her sisters and enact revenge on the violent men she's come to despise. But is she willing to go back to Scopuli and face the consequences of her past decisions? And will Proserpina forgive her for all that she's done?

Told in alternating timelines, Those Fatal Flowers is a powerful, passionate, and wildly cathartic love letter to femininity and the monstrous power within us all.
