For as long as she can remember, Ella has longed to feel at home. Orphaned as a child after her parents’ murder, and afflicted with hallucinations at dusk, she’s always felt more at ease in nature than with people. She traveled from Bangladesh to Brooklyn to live with the Saleems: her uncle Anwar, aunt Hashi, and their beautiful daughter, Charu, her complete opposite. One summer, when Ella returns home from college, she discovers Charu’s friend Maya --- an Islamic cleric’s runaway daughter --- asleep in her bedroom. 
 
As the girls have a summer of clandestine adventure and sexual awakenings, Anwar --- owner of a popular botanical apothecary --- has his own secrets, threatening his 30-year marriage. But when tragedy strikes, the Saleems find themselves blamed. To keep his family from unraveling, Anwar takes them on a fated trip to Bangladesh, to reckon with the past, their extended family, and each other.
