"MacMahon writes with such beautiful simplicity, conjuring real and complex people straight off the page ... subtle and authentic" - Claire Fuller On opposite sides of the world, half-siblings Cassie and Christo have built their lives around work, intent on ignoring their painful past. When a dramatic storm in Galway hits the headlines, they're drawn back there to revisit a glorious childhood summer, the last before their mother died.

But their journey uncovers memories of a far less happy summer - one that had tragic consequences. Confronted with the havoc their mother left in her wake, Cassie and Christo are forced to face their past and - ready or not - to deal with the messy tangle of parental love and neglect that shaped them. The Home Scar is a luminous and precise story about the inheritance of loss and the possibility of finally making peace with it.
