My reading list is definitely dominated by fiction. I’d go so far as to say that I’m fairly selective about what non-fiction I read. This seems to be reflected in this category because although I only read 15 non-fiction books in 2018, four of them are highlighted below. The non-fiction I read this year was really good.
Honourable Mention:
Rest, Play, Grow – Deborah MacNamara (Aona Books, 2002)
The Weight of Glory – C.S. Lewis (Harper Collins, 2001)
And No Birds Sang – Farley Mowat (McClelland & Stewart, 1979)
And the Winner:
Your Heart is the Size of Your Fist – Martina Scholtens (Brindle & Glass, 2017)
As good as the other books were, this was the clear winner. I read Scholtens’ memoir/exploration of medicine in January and have thought about it all year. I’ve recommended it to multiple friends and heard nothing but good reviews in response. (In fact, if you borrowed my copy, let me know. I’ve lost track of it…) Well-written, compelling, thoughtful, and timely, I can easily recommend this one and won’t be surprised if I find myself re-reading it down the road.

I don’t read a lot of non-fiction, either, but I would really like to read this one!
I don’t either but this one is really good. And everyone I know who has read it enjoyed it too!
