Catnip

For all his life, Sol has believed he's only worthy of affection as long as he's useful—and he intends to prove his ultimate use by restoring a colony on Venus as a new home for his friends and lovers. But upon arriving, he realizes there's more here than he bargained for. For one, the resident artificial intelligence wants to make friends with him. For another, the nanites want to completely change his body... and in the process reveal her true self. Stuck (or perhaps blessed?) with a new form, she must find out what it means to live, to be loved for who she is rather than her work.
Catnip is a space exploration novel about a trans woman's journey to find herself and what it means to be loved for who she is, with the help of her polycule and a lesbian AI.
