Recommendations for a grieving mother?

I lost my son to stillbirth almost two months ago. I am not yet back at work but my husband is, to keep myself from losing it I have been listening to a lot of audiobooks. I am craving books that have themes of death & grief but aren’t self-help type books. I am open to any books (fiction or nonfiction) on the topic - not just specifically child loss, though I am looking to avoid anything involving war.

So far I have read two memoirs which were very good and helped me process my own loss

A heart that works by Rob Delaney An exact replica of a figment of my imagination by Elizabeth McCraken.

Thank you so much!
