JessamynBook 46: The Mars House. So much going on in this book! A man immigrates to Mars as the Earth becomes uninhabitable. He learns that people who are "Earthstrong" (i.e. born on Earth with more muscle mass and adapted to more gravity) are in a weird class of "dangerous" people and treated accordingly. Mars natives live in a genderless society where they've been genetically adapted to a planet that is dusty and cold. Then there is some palace-intrigue type stuff. Also mammoths. Quite good.
