Kaleidoscope - Danielle Steel

When Sam Walker returned from the front lines of World War II, bringing with him his exquisite French bride, no one could have imagined that their fairytale love would end in such a shattering tragedy. Nine-year-old Hilary, the eldest of the Walker children, clung desperately to her two sisters: five-year-old Alexandra and baby Megan. However, before the year was out, they too would be painfully wrenched from her tender arms. Cut off from every loving warmth, Hilary swore she would one day track down the man who had destroyed her family, and find her beloved sisters again. But could they risk everything to confront a dark, forgotten past?

John Chapman, lawyer, prestigious, private investigator - chosen to find the sisters - embarks on a labyrinthine trail which leads him to Paris, New York, Boston and Connecticut, knowing that at some time in their lives, the three sisters must face each other - and the final, most devastating secret of all . . .
