When the residents of St Kilda ask to be evacuated from their remote island home in the summer of 1930, it’s in search of a better life on mainland Scotland compared to the scratch existence on their mountain in the sea.

For eighteen-year-old tomboy Effie Gillies, it’s a bittersweet departure. She’s the best young climber on the island, as skilled and brave as any of the men. But it is Effie’s expansive knowledge of local bird life that leads her to take up a position as curator of Dumfries House’s ornithological collection – and back into the arms of Lord Dumfries’ son and heir, Sholto.

During her last summer on St Kilda, Effie had been Sholto’s guide, and their attraction had seemed irresistible. But, in the glamorous polite society of Ayrshire, it is clear they are worlds apart. When a body is discovered on the island, soon after the evacuation, a scandal erupts as Effie is implicated. Sholto knows she’s keeping secrets – but are they even her own?

The Last Summer is the first in an epic, sweeping historical series by Sunday Times bestseller Karen Swan, set in and around the Scottish island of St Kilda.
