Book three in Rajaniemi's Flambeau trilogy.

The first line: "Alone on the timeless beach, Joséphine Pellegrini finds herself disappointed by the end of the world." After all her hard work. A bit of a fizzer as it turned out.

How the complaining hero saved the earth from dissolution. It got a bit too 'deus ex machina' for me. And then it finished with a chapter that should have been called, 'Be careful what you wish for' as they dropped the hero into a life of regret.
