By the time fifteen-year-old Pia arrives at her father Stephen’s luxury apartment in Manhattan and meets his new, younger wife, Kate, she has been shuttled between her parents’ disparate lives—her father’s consuming work as a surgeon, her mother’s relentless drive against a ticking ecological clock—for most of her life. Moving between cultures with seeming ease, Pia arrives in New York poised for a rebellion, just as COVID sends her and her stepmother together into near total isolation. Even as Kate fails to parent Pia—one of her sixteen-year-old students is already caring for a toddler full time. Athyna’s love for her nephew, Marcus, is a burden that becomes heavier as she struggles to finish her senior year online. When their lives collide, Pia and Athyna spiral toward parallel but inescapably different tragedies.
