Winterson has her own unmistakeable voice, tuned to express her obsessional preoccupation with sexual passion raised to the power of revealed religion. (...) The whole book is a kind of chant. It is a playful addition to the Winterson oeuvre. Yet it is not a slight work so much as, homonymically, a work of sleight- - a word for which the Shorter OED gives six definitions, ranging from trickery to wisdom, all of which apply to The.PowerBook.
