Grief is the Thing With Feathers - Max Porter

Max Porter is some kind of crazy genius with his unique take on a single topic. I was given this book by my friend Richie in Bristol as he says this is his ‘go to gift book’, which I really like the idea of. (Thank you Richie, I loved it). What is your ‘go to gift book?’ And what are the criteria I’m curious… (I need to choose mine as well). 
Like new copy from the UK.
