Family Money — Doris Shannon

Elizabeth, the poor relation of the proud and wealthy Meredith family who must endure the life of a drudge, embarks on a quest for revenge against her arrogant relatives, in a story of betrayal, passion, and the downfall of a powerful dynasty.

Poor Cousin Elizabeth - a woman cheated out of her rightful share of the Meredith fortune, living like a servant in the great New York mansion that should have been hers. She knew how to smile ingratiatingly at William, arrogant master of the household, and to hide her hatred of Alan, the spoiled favorite son. But she didn't know how she was to get back what rightfully belonged to her. Until Judith - William's beautiful, pampered new wife, a woman too young and wild for a husband twice her age. She would befriend Elizabeth - and then betray her. But in that betrayal she would reveal to Elizabeth a powerful secret - the key to a poor woman's sweet dreams of having everything her heart desired - especially sweet revenge.
