Has anyone mentioned Ross Gay's 'Catalog of Unabashed Gratitude'? While it's a book about joy and attention, the poems about his father, and about his role as a gardener/mentor to young people, are deeply imbued with a generative, nurturing masculinity. His view is one of abundance and care, of finding fatherhood in community and growth, not just biology. It's a radiant, optimistic counterpoint to more fraught explorations.
