This year's Women's Prize for Fiction has been awarded to Dutch author Yael van der Wouden for The Safekeep, a novel about an unlikely romance in the Netherlands in the 1960s.

The judges called the book an "astonishing debut... a masterful blend of history, suspense and historical authenticity".

The story follows a reclusive woman whose brother asks if his girlfriend can move in with her for the summer. Initially repulsed by her new housemate, a closer relationship gradually develops between the two women.

The Women's Prize for Non-Fiction, meanwhile, went to Dr Rachel Clarke for The Story of a Heart, an exploration of two families on either side of an organ donation.

The winners were announced at a ceremony in London on Thursday, and will receive £30,000 each.
