Set in a universe where time is a resource – coveted and exploited, the key to power and privilege – comes a dazzlingly inventive sci-fi fantasy romance by a bestselling Irish author.

"Skipshock isn’t just a book. It is, literally, a new world to dive into, and one so exquisitely conjured that you feel you live there for a while. A suspenseful, romantic, charming and really unique tale." – Matt Haig

Margo is on a train to a new boarding school when she slips into another dimension, passing from the height of Irish summer into the chill of an alien winter, from a 24-hour day to one that begins and ends in just six hours. From a stranger on the train – a travelling salesman by the name of Moon – she learns that New Davia is part of a world scarred by uprisings, travel bans and world sealings. Power is determined by time – who has it, who doesn’t, and who has the freedom to travel between time zones.

Can Margo find a way to get back home – or will she choose to stay in a world where her teenagehood is slipping away faster than ever before, but where she may have found the only person with whom she would choose to spend eternity?
