The titular character in Nnedi Okorafor’s novella is the first of the Himba people to leave Earth to travel to Oomza University, the most prestigious institution of higher learning in the galaxy. But when her ship is attacked by the Meduse, a tentacled and violent alien race, Binti is transformed. There are echoes of Octavia Butler’s Lilith’s Brood series here, but Okorafor’s imagination and ambition stand on their own.
