One book that was helpful for me after my dad died was Garson Kieler's book "Good Poems for Hard Times" [1]. It's a beautiful anthology of poems that helps with working through life, loss, and grief. Each time I open it, a different poem speaks to me and has helped me grapple not only with my loss, but with my own life.
