In What to feel, how to feel, Shane Neilson dazzles in the lyric essay form. Focusing on non-neurotypicality, Neilson investigates his supposed difference of self while also holding to account society's construction of that difference, moving from his early childhood to adulthood and then back again in terms of a neurodivergent fathering of his own son. Covering subjects that have yet to receive attention in Canadian literature, including how the medical profession discriminates against its own, Neilson's poetic accounts of stigma and self-discovery interleavened with literary history mark a first in our letters.
