The Pembroke coast was a pleasant place for a late holiday, but Nicola's thoughts were all on returning to her librarian's job in Surrey and, very soon, getting married to Laurie Barnwood, her secure childhood sweetheart.

Suddenly, one letter from Laurie changed everything. Without her realising it, her father's recent remarriage had introduced new currents of possessive jealousy into the family and Laurie himself is going to marry Nicola's pretty clinging young step-sister.

To run from a world which had once seemed so contentedly settled and now has no place for her, Nicola is happy to escape back to Wales and a job in the clifftop hotel which will occupy all her waking energies while her numbed mind grapples with the shock of Laurie's loss.

Ironically, once he is married, it is Laurie who seems loth to lose contact with Nicola, and she is too trusting to see what complications this may bring. Too soft, would be the opinion of Simon Ashtead, local antiquarian bookseller and a coolly detached observer of life's foibles. Simon offers a feather-weight friendship, suited to Nicola's vulnerable mood. Before she can embark on a deeper relationship with anyone she realises it is up to her to negotiate the shattering rocks and falls on her life's river and emerge in a new stretch of water, her own person.
