Fires in the Forest — Marina Oliver

Nicola has just graduated in French, and takes a summer job in the New Forest as tutor/companion to the wealthy seventeen-year-old Sarah Frayn, before she starts a bi-lingual secretarial course. Unpredictable and volatile, Sarah rebels against the harsh rules imposed by her half-brother Robert, especially his prohibition on meeting her boyfriend. Nicola has clashed with Robert before, but when various calamities afflict the family, she is thrown into closer contact with Robert.
