When I picked up Barkskins (2016) by Annie Proulx, I expected a book about trees. And trees there most certainly are growing among its pages, although not in the Richard Powers’ The Overstory sort of way; trees are not characters and the tree-inspired figurative constructs with which Proulx crafts her novel differ greatly from Powers’. What I found was something more than trees but certainly relating to them both as a subject and a metaphor. Proulx’s multi-generational story spans the course three and half centuries. In that sense, it is tree-like; many arboreal species live much longer than that. Spread over so much time, this hefty novel (it exceeds 700 pages) comes to life with a large cast of characters, so large that the family trees at the book’s end are useful, even necessary. At the heart of all their stories is a familial link to trees.
