Book excerpt: In To the Island of Tides, Alistair Moffat travels to – and through the history of – the fated island of Lindisfarne. Known by the Romans as Insula Medicata and famous for its monastery, it even survived Viking raids. Today the isle maintains its position as a space for retreat and spiritual renewal. Walking from his home in the Borders, through the historical landscape of Scotland and northern England, Moffat takes us on a pilgrimage in the footsteps of saints and scholars, before arriving for a secular retreat on the Holy Isle. To the Island of Tides is a walk through history, a meditation on the power of place, but also a more personal journey; and a reflection on where life leads us.
