When Rowan and Isabel return to the coastline where they spent a blissful summer, almost fifty years before, it's with a very different purpose. Isabel is dying; she wants it to be here, now. As darkness falls, their past collides with the present and Rowan is called upon to make a sacrifice that will preserve their unity forever. Passionate, searing and poetic 'The Mapmaker' examines a life and love that, just like all of ours, is all too fleeting.
