This is everything that Winterson is great at—it examines the nature of love, reality, time, death, family, gender, sexuality, insanity v. sanity, and in this case, physics. At times it’s a harder read than her other works because of the physics focus… as an English person, most of that went quite over my head. It’s beautiful, resonating, and poetic. It is of the calibre of The Passion and Sexing The Cherry.
