Louise Banks learns Heptapod B
Linguist Louise Banks is recruited to decode the heptapods, aliens who appear through 'looking glasses', and discovers their written language (Heptapod B) is semasiographic: each sentence is a single sprawling glyph whose first stroke already requires knowing how it ends. As she becomes fluent, she begins remembering her future, including the birth of a daughter by physicist Gary Donnelly and that daughter's death in a climbing accident at twenty-five. Knowing all of this, she still says yes when Gary asks if she wants to make a baby, and the story is narrated to the daughter in a tense that mixes past and future.
