Consent - Annabel Lyon

Saskia and Jenny are twins, alike in appearance only: Saskia has a single-minded focus on her studies, while Jenny is glamorous, thrill-seeking and capricious. Still, when Jenny is severely injured in an accident, Saskia puts her life on hold for her sister.

Sara and Mattie are sisters with another difficult dynamic: Mattie needs almost full-time care, while Sara loves nothing more than fine wines, perfumes and expensive clothing, and leaves home at the first opportunity. But when their mother dies, Sara must move Mattie in with her. Gradually, Sara and Saskia learn that both their sisters' lives, and indeed their own, have been altered by the devastating actions of one man...

In turns razor-sharp, provocative and precise, Consent is a blistering novel of sisters and their knotty relationships, of predatory men and sexual power, of retribution and the thrilling possibilities of revenge.
