The Third Child — Marge Piercy

Under her mother's constant scrutiny and lost in the shadow of her famous senator father, Melissa is the third child in the politically prominent Dickenson family, where ambition comes first and Melissa often comes last. In college, she meets Blake, a man of mixed race and apparently unknown parentage. His adoptive parents are lawyers whose defense of death-row cases in the past brought them head-to-head with Melissa's father when he was the governor of Pennsylvania.

While Melissa and Blake's attraction is immediate and fiery, a dangerous secret lurks beneath their relationship -- one that could destroy them ... and their families.

Provocative and beautifully written, and dealing with themes of love, honesty, identity, and the consequences of ambition, The Third Child is a remarkable page-turner.
