It’s like Flatland crossed with The Pilgrim’s Progress. All of this is beautifully illustrated by the Croatian artist Tomislav Tomic. There’s no faulting Ukrainian author Shyfrin’s ambition. His novel encompasses wormholes, suicide bombers, the Jewish diaspora, wave-particle duality, the nature of God and a whole lot else besides. Whether it’s successful in unifying these big ideas is another matter. The book’s tone of allegorical mysticism may enthral some but leave others bemused.
