The characters here are so delightfully rich despite the small space they occupy, and Gailey does a great job of making you feel Esther's dilemma and development. I love how you get so many different flavors of lesbian and also queer woman. 

Of course, the genre is an Issue and on the scale of "grappling with settler colonialism" I will say there is none; there are no explicitly Native characters, which in some ways is a good move, and the question of settler colonialism and its continual presence is not raised, nor is its violence interrogated beyond reference to the way the settler state in its dystopian form works. Native absence is felt particularly because of the genre and setting.
