This novel follows Donal O'Brien, a journalist and writer who recently blew up his seemingly stable, happy life by booking a monthslong journey on a cargo ship with the ostensible purpose of writing about the experience. When a pandemic and nuclear annihilation strike in quick succession, Donal and the ship's crew realize they're on their own. This book is a mashup of two of my favorite tropes - postapocalyptic fiction and locked-room mysteries. I started reading it one morning and could not put it down until I was finished, which I did that same afternoon -- even though I was at work! If you've never watched YouTube videos of cargo ships at sea, I recommend watching a couple of those to get even more of a sense of what Donal and the crew are experiencing. Even if you don't watch those videos, though, Dieppe creates such a tense, claustrophobic atmosphere that your heart will begin to race together with Donal's at the dawning realization that someone on board is not who they seem.
I also really liked the depiction of the society that developed on board the ship. Despite the absence of a wider civilization, racial and ethnic tensions rear their ugly heads in a way I found very true to life. Just as the crew are trapped on the ship and trapped in the doldrums, so too are they trapped by pre-existing tensions and hierarchies. We, as humans, don't seem to be able to escape them. Gender is addressed less, but affects the plot in a surprising way. Donal's explorations into the crew's lives and personalities add dimensionality to the characters, but more importantly, they help to illustrate these themes without making the book at all didactic. It's the societal realism and respect for the uniqueness and individuality of the characters that set this book apart from your average mystery or apocalypse story.
I feel like I discovered an unknown gem, and I want everyone to read this one.
