TWIN TIDES

Hien Nguyen

Long-lost identical twins Aria and Caliste are beckoned to Les Eaux, Minn., where they unravel the mystery behind their mother's death, discover a ghoul haunting the waters of the small town, and wade through the betrayal that ultimately separated them
Caliste Ha and Aria Nguyen couldn't lead more disparate lives. Caliste, heiress and fashion influencer, lives in a Los Angeles high rise and spends her days curating a glossy feed to camouflage her strained place within her family's empire. Meanwhile, Aria's barely surviving her first year at Georgetown, and has taken to moonlighting as an academic ghostwriter for her wealthy peers to help care for her sick aunt. There is one thing uniting them: the fact that both their mothers went missing years ago. When the two arrive in sleepy Les Eaux, Minnesota and meet for the first time, a moment of confusion befalls the investigation. The girls are identical twins, and suddenly, the gravity of their mother's death takes on new meaning. As the sisters unravel their tangled family histories, they discover threads woven through the war, a ghoul haunting the waters of Les Eaux, and a betrayal that drowned both of their families.

Orphan Aria Nguyen has never known more than a life scraping by with her aunt in the suburbs of DC. Meanwhile, Caliste Ha lives a life of lonely luxury on the West Coast as an influencer and daughter of a wealthy entrepreneur. When both girls receive notice that their mother's body has been found in the strange town of Les Eaux, Minnesota, they discover the truth of their twinship and uncover deep family scars. Nguyen's paranormal thriller debut explores generational grief and trauma stemming from the Vietnam War. Faced, too, with modern-day implications of patriarchal violence, Aria and Caliste must not only navigate their newly discovered sisterhood but also get to the murky bottom of their mother's disappearance and death. If their mother vanished years ago, why is her body discovered only nowand why does she still maintain such a youthful appearance? A series of haunting questions that only uncover further mysteries makes this a chilling story fit for fans of Lily Meade's The Shadow Sister (2023).
