So while this is a book about fighting back, in the end this is a book about love. The songbirds and the salmon need your heart, no matter how weary, because even a broken heart is still made of love. They need your heart because they are disappearing, slipping into that longest night of extinction, and the resistance is nowhere in sight. We will have to build that resistance from whatever comes to hand: whispers and prayers, history and dreams, from our bravest words and braver actions. It will be hard, there will be a cost, and in too many implacable dawns it will seem impossible. But we will have to do it anyway. So gather your heart and join with every living being. With love as our First Cause, how can we fail?
