Room by Emma Donoghue
I’ve written about this book on this blog before (you can find that post here). This stands out for me because it affected me strongly while I was reading and that impression has lasted – it made a dent in me, which didn’t fade slowly away like a fingerprint in dough. It stayed, like a dent in a car bonnet. The reading experience did what all great art and fiction does for us: it changed me, in a tiny way, for having experienced it.
(I’m interpreting ‘last year’ to mean 2013. )
