Rowan and his three children (Raff, Fen and Orly) are caretakers of what used to be a small research island located close to Antarctica. Because of rising waters, the island is going under. Everyone else has left and the family is sticking it out until the last boat comes to pick them up. Communications are down, and there is no way to get in touch with anyone off the island. There is a storage facility for seeds from all over the world, but after an intense storm, the generator to keep the storage system cold has gone down, threatening their survival.
The storm also brought in an injured woman. Fen, Rowan's seventeen-year-old daughter finds her near shore and swims out to save her. The woman's name is Rowan, and she said she came to the island looking for her husband. Everyone is acting cagey and it is clear that no one is telling the full truth.
Instead of Fen living with her family, she sleeps alone in the boathouse down by the water. The youngest boy Orly is basically a plant encyclopedia, and he follows Rowan around the living quarters like a lost little puppy. The oldest brother, Raff, and his father are more difficult to read. As Rowan's injuries improve, she is able to explore around the island and try to figure out what might have happened to her husband. Raff said he left on the last ship, but Rowan never heard from him. When she finds her husband's hidden passport, she knows they are lying to her.
Throughout this novel, the effects of climate change are glaringly obvious. First is the rising ocean water forcing the evacuation of the island. Second, is the concern for the seed bank. With plants being devastated by the warmer temperatures, the seed bank was a safeguard so the Earth would not lose too much diversity. Unfortunately, with the seed bank getting warmer as well, there are only so many seeds they can save. Finally, Rowan's dream home that she'd spent years building in Australia had burned down from intense fires made worse by climate change.
All of the characters have faced or are facing losses so profound and heart wrenching, and all this is tied together with the losses we have and will have from climate change. Yet the book wants us to keep caring, keep loving, and not give up.
"Not only do I feel this weight, I see the future laid out before me. A vast stretch of crops and nothing else, nothing wild or natural, and even these neatly planted rows threatened on all sides by flame and flood. All of earth, a wasteland." (120)
"There is such peril in loving things at all, and he feels sort of proud, in fact, that he just keeps on doing it." (294)
"But here is the nature of life. That we must love things with our whole selves, knowing they will die." (232)
