an incredible read https://www.goodreads.com/book/show/25899336-when-breath-becomes-air also have heard great things about https://www.goodreads.com/book/show/38212121-from-here-to-eternity keeping an eye on this thread since i'd like some more suggestions too
I've found this book by Francis Weller most helpful for grieving: "The Wild Edge of Sorrow: Rituals of Renewal and the Sacred Work of Grief" https://www.penguinrandomhouse.com/books/250673/the-wild-edge-of-sorrow-by-francis-weller/
nothing worked for me such as this classic - https://www.goodreads.com/en/book/show/208123
Can recommend grieving books for kids, parents, and parenting grieving kids while grieving. Not sure if this is what you’re asking for
Don't Go Where I Can't Follow. It's a graphic novel / mixed media work. Really, devastatingly good.
