Mhairi Anne Bain owns only two things: a gun with no bullets and her identity papers.
The world is a shell of what it once was. Now, you must prove yourself worthy of existence at every turn, at every border checkpoint. And if you are going to survive, your instincts will become your most valuable weapon.
Mhairi has learnt the importance of living her own story, of speaking to no one. But then she meets a young boy with no voice at all, and finds herself risking everything to take him to safety.
And so Mhairi and the silent boy travel the road north. But there are rumours that things in Scotland have changed since she has been away. What Mhairi finds there is shocking and heart-breaking, but might finally re-connect her to her sense of self and to the possibility of love.
