Almost a year to the date of his parents' death, botanist Alfred Homer, ever hopeful and constantly surprised, is invited on a road trip by his parents' friend Professor Morgan Bruno. Professor Bruno wants company as he tries to unearth the story of the mysterious and perhaps dead poet John Skennen. But Days By Moonlight is also a journey through an underworld that looks like southern Ontario, a journey taken during the hour of the wolf, that time of day when the sun is setting and the traveller can't tell the difference between dog and wolf, a time when the world and the imagination won't stay in their own lanes. Alfred and the Professor encounter towns where Black residents speak only in sign language during the day and towns that hold Indigenous Parades; it is a land of house burnings, werewolves, witches, and plants with unusual properties.
