Spanning the years 1900 to 1977, The Covenant of Water is set in Kerala, on South India’s Malabar Coast, and follows three generations of a family that suffers a peculiar affliction: in every generation, at least one person dies by drowning—and in Kerala, water is everywhere. At the turn of the century, a twelve-year-old girl from Kerala’s long-existing Christian community, grieving the death of her father, is sent by boat to her wedding, where she will meet her forty-year-old husband for the first time.

Cyril Avery is not a real Avery - or at least that's what his adoptive parents tell him. And he never will be. But if he isn't a real Avery, then who is he? Born out of wedlock to a teenage girl cast out from her rural Irish community and adopted by a well-to-do if eccentric Dublin couple via the intervention of a hunchbacked Redemptorist nun, Cyril is adrift in the world, anchored only tenuously by his heartfelt friendship with the infinitely more glamourous and dangerous Julian Woodbead.

Olivia McAfee knows what it feels like to start over. Her picture-perfect life—living in Boston, married to a brilliant cardiothoracic surgeon, raising their beautiful son, Asher—was upended when her husband revealed a darker side. She never imagined that she would end up back in her sleepy New Hampshire hometown, living in the house she grew up in and taking over her father’s beekeeping business. Lily Campanello is familiar with do-overs, too. When she and her mom relocate to Adams, New Hampshire, for her final year of high school, they both hope it will be a fresh start.

When Pierrot becomes an orphan, he must leave his home in Paris for a new life with his aunt Beatrix, a servant in a wealthy Austrian household.

Pierrot is quickly taken under Hitler's wing and thrown into an increasingly dangerous new world: a world of terror, secrets, and betrayal from which he may never be able to escape.
