Adventure in nature (Sapphic Reading Challenge #40)

This week’s Sapphic Reading Challenge features sapphic books with an adventure in nature. 

The book’s plot revolves around an outdoor adventure, e.g., hiking, kayaking, rafting, sailing, rock climbing, snow-shoeing, etc., or just trying to survive in nature.

It could be a planned trip the characters are taking together for fun, or it could be a fight for survival in the wilderness.
