A black hole is tearing apart the solar system.
Mairead's life is already in pieces.
The Earth has less than a year to survive.
Asteroids rain hell; earthquakes rattle cities; manic tides swamp coasts. Mairead intends to give herself to the erratic waves that erode her remote Irish island, the same that claimed her child. When Gavin, an American, arrives to scatter his father's ashes, she becomes torn between wanting for life and death.
Despite the tides, fuel shortages, and closing borders that threaten to trap him on the island, Gavin can't seem to scatter the ashes. He doesn't know how to let go any more than Mairead does and they find a strange comfort in their confusion.
Their affair draws Mairead back to the world of the living, but the longer Gavin stays, the more it seems there might be a future for them. There is no future.
Life closes down around them. The world they know shreds. Life drains into an inescapable abyss. And yet Mairead fights, both the gravity of her grief and the restless, dissonant desire to find some kind of peace no matter how brief.
