Sidney Sheldon's The Tides of Memory

How far would you go to protect the ones you love?On the surface the De Vere family appear to have it all. Wealth, political power, and idyllic life split between their London mansion, Oxfordshire country house and their idyllic, sprawling Martha's Vineyard estate.

When the mistakes of youth refuse to stay buried, and generation old hatreds resurface, the De Veres find themselves on the brink of losing everything. How far will each of them go to conceal the truth and protect the family?
