Book Summary

An eclipse is coming, and with it, a young woman's one chance to save the world, in this gripping speculative environmental thriller.

Fin grew up by an observatory, learning about telescopes and planets, inspired by the passions of her mother and father, then leaders in their fields of astrophotography and astronomy. Those days are long over. Now Fin, her mother Dianella, and a band of outliers live deep off the grid, always on amber alert and always ready to run.

In the outside world, things are not good: extinctions and a loss of diversity threaten what's left of the environment. With a new disaster looming, Fin finds herself thrust into an unlikely partnership with a stranger who has appeared in their camp. Terry is one of a new breed of evolved humans, the Incompletes, who are widely distrusted. But the pair will need to work together during a dangerous journey if they are to play their part in a plan to help restore the natural world―and humankind.

The Thinning is an exquisitely written novel of both nature and urgent psychological suspense. There are echoes of Margaret Atwood in its themes about fertility, and it is also reminiscent of Rumaan Alam's Leave the World Behind, Megan Hunter's The End We Start From, and Joanne Ramos's The Farm.
