A Secret Too Far — Margaret Mayo

Heartbroken Rianne had built a new life for herself after her boyfriend, Javier Marquez, walked away from her without a word of explanation. Now, six years later, she bumps into him while on holiday in Spain and cannot believe it when he pretends not to know her.

Back home in England she tries to get on with her life, but once again he turns up and this time he tells her the truth.
