Where Are the Kings by Donal Ryan review – a timeless tale of family sorrows and joys

Something is happening to literary time. In the last fortnight I’ve read new or forthcoming novels about a mirror universe where history runs backwards (Under Story, Chloe Benjamin), an agency that offers appointments with the past (Time Travel for Beginners, Jaclyn Moriarty), and a young woman who’s genetically untethered from linear life (Audrey Niffenegger’s long-awaited sequel to The Time Traveller’s Wife, out in October). And these are just the latest books to meddle with the fourth dimension. There are dozens: from Solvej Balle’s On the Calculation of Volume series and Toshikazu Kawaguchi’s Before the Coffee Gets Cold, to Kaliane Bradley’s The Ministry of Time. Time is losing the plot – or perhaps it’s the other way around.

I have an armchair theory about all this counterfactual longing: the lure of the do-over. The present feels like a corrupted timeline. If only we could find the glitch.
