A Natural History of Transition is a collection of short stories that disrupts the notion that trans people can only have one transformation. Like the landscape studied over eons, change does not have an expiration date for these trans characters, who grow as tall as buildings, turn into mountains, unravel hometown mysteries, and give birth to cocoons. Portland-based author Callum Angus infuses his work with a mix of alternative history, horror, and a reality heavily dosed with magic.
