Every summer, in a rambling castle in Kenmare, south west Ireland, the TV crews descend to film the nation's favourite cookery competition. For Diana, a celebrated TV chef, it's a way to keep her castle running. But this summer, it will be different.
There's a lot more at stake than the perfect muffin. Bea, the cupcake queen, is determined to remind everyone why she deserves her own TV show, at whatever cost. Connor, the bad boy of the restaurant world, is determined to put his lurid past behind him and turn over a new leaf.
And food blogger Darcy finds that returning home to the castle means stirring up some long-buried feelings for someone she'd never quite forgotten.
