Tropical Nurse — Margaret Barker

A six-month nursing contract in West Africa will give Kate Matthews just the time she needs to remove any doubts she has about her engagement to David, her childhood sweetheart.
At first she is blissfully happy to be back in Ikawa where she spent the happiest days of her childhood. England - and David - seem very far away.
Yet when her new boss, the arrogant Dr. Richard Brooks echoes her doubts, why is she suddenly so determined that nothing he says will stop her marriage?
