In the too-close-for-comfort future, an environmental justice organizer named Giselle and her billionaire baby brother Elon are (unsurprisingly) at odds. She believes the earth and her people are worth saving; he marvels at the potential in starting over somewhere new. Meanwhile, his virtual assistant Ava has some very nuanced opinions of her own. (Who programmed her to talk so much?!) Set against the backdrop of a rapidly-accelerating climate crisis, brother sister cyborg space explores political divisions within families, an expanding definition of humanity, and what we'll do when time runs out.
