This impressive debut novel, longlisted for the 2020 Booker Prize, takes its premise and inspiration from ten of the best-known thought experiments in philosophy—the what-ifs of philosophical investigation—and uses them to talk about love in a wholly unique way.

Married couple Rachel and Eliza are considering having a child. Rachel wants one desperately, and Eliza thinks she does, too, but she can’t quite seem to wrap her head around the idea. When Rachel wakes up screaming one night and tells Eliza that an ant has crawled into her eye and is stuck there, Eliza initially sees it as a cry for attention. But Rachel is adamant. She knows it sounds crazy—but she also knows it’s true. As a scientist, Eliza is skeptical. Suddenly their entire relationship is called into question.

What follows is a uniquely imaginative sequence of ten interconnecting episodes—each from a different character’s perspective—inspired by some of the best-known thought experiments in philosophy. Together they form a sparkling philosophical tale of love lost and found across the universe.

From the Booker Prize-longlisted author of Love and Other Thought Experiments comes a masterful and gripping thriller about truth, silence, and the weight of the past.

Isobel lives an isolated life in North London, where she works at a nearby library. She feels safe, so long as she keeps to her routines and doesn’t let her thoughts stray too far into the past. But a newspaper photograph of a missing local schoolgirl and a letter from her old teacher send her spiraling and bring back the trauma of what happened years ago, when she was a pupil at The Schoolhouse.

The Schoolhouse was a 1970s experimental school where the usual rules did not apply. Life there was a dark interplay of freedom and adventure, violence and fear. It was here that Isobel learned that some truths should never be revealed. But try as she might, the truth is coming for Isobel, and everything and everyone she has tried to protect are now at risk.
