I picked up Can’t We Talk About Something More Pleasant after reading a New York Times article on excellent graphic novels/memoirs, because it had been a while since I read one of my favorite genres. 
And boy, this one really punched me in the gut. My mom died almost exactly two years ago, and thankfully I didn’t have quite this same experience - but anyone who has dealt with the worry in navigating the morass of caring for an elderly parent who is dying will absolutely identify with this account. Our system is so broken when it comes to elder care, and I remember thinking the same when I read, We all Want Impossible Things by Catherine Newman. The fiscal and emotional cost that goes into palliative care is beyond wasteful and cruel. 
There were alternating moments of laughter and great sadness, with a lot to unpack on how we reconcile a traumatic relationship with a person who is dying or had died. Heavy stuff, but I highly recommend.
