For Ava Fisher, the backdrop to all her sun-drenched memories is her grandmother's summerhouse in the sleepy Spanish seaside town of Mariposa. Returning for one last summer, Ava throws herself into a project her grandmother would be proud of. Café Estrella, once the heart of the sleepy seaside village, now feels more ramshackle than rustic. Away from the exhausting juggle of London life, Ava realises somehow her life has stopped being happy. But being back at the Summerhouse by the sea could be the new beginning she didn't even realize she needed.
