Skating on Mars / Caroline Huntoon.

Enhanced descriptions from Syndetics:

A heartwarming debut from author Caroline Huntoon about a young figure skater discovering who they are on and off the ice.

Life isn't easy on twelve-year-old Mars. As if seventh grade isn't hard enough, Mars is also grappling with the recent death of their father and a realization they never got to share with him: they're nonbinary. But with their skates laced up and the ice under their feet, all of those struggles melt away. When Mars' triple toe loop draws the attention of a high school hot shot, he dares them to skate as a boy so the two can compete head-to-head. Unable to back down from a challenge, Mars accepts. But as competition draws near, the struggles of life off the rink start to complicate their performance in the rink, and Mars begins to second guess if there's a place for them on the ice at all.

Skating on Mars is a tender examination of grief and a hopeful middle grade tale of self-discovery.
