Island Calling by Francesca Segal

On remote Tuga de Oro, vet Charlotte Walker's caseload of donkeys, cows, and ailing lizards has only increased. She still can't believe the humiliating truth about her father. Probably, she ought to feel worse than she does. But the islanders have taken Charlotte to their hearts and somehow, between days on the farms and nights with a new love interest, she's content to remain in blissful retreat from her real life in London. Just for now. But real life hits the island with the force of a tropical storm: Charlotte's mother arrives. Lucinda Compton-Neville knows an identity crisis when she sees one, and has come to haul her daughter back on course: back to England, back to her career, back home where she belongs.
