His fourth poetry collection, "Pain and Passing: Islamic Poems of Grief and Healing" (Swansea: Claritas Books), appeared in early 2018. It deals with the death of his wife Kathy. In an interview, Hayward described this as “undoubtedly the hardest book I’ve ever written," adding that it was nonetheless a cathartic experience. “After Kathy died I felt I had to write; to release what was fighting inside to get out. I wrote every day, even when tired or busy, and tried to stay responsive to the poems’ need for life."
