Something New Under the Sun is a 2021 novel by American writer Alexandra Kleeman.

The novel takes place in the near future in which California has been rendered nearly uninhabitable by climate change.

Kleeman wanted to include climate change in her novel in a way that was portrayed it as "[...feeling] more present and bodily".

[1] She set the novel in California, inspired by her childhood in the southern portion of the state.

[2] Kleeman deliberately wrote the opening of the book as a "realist novel" and made the story more "speculative" as it continued.
