The seventh son / Sebastian Faulks.

When a young American academic Talissa Adam offers to carry another woman's child, she has no idea of the life-changing consequences. Behind the doors of the Parn Institute, a billionaire entrepreneur plans to stretch the boundaries of ethics as never before. Through a series of IVF treatments, which they hope to keep secret, they propose an experiment that will upend the human race as we know it. Seth, the baby, is delivered to hopeful parents Mary and Alaric, but when his differences start to mark him out from his peers, he begins to attract unwanted attention. The Seventh Son is a spectacular examination of what it is to be human. It asks the question- just because you can do something, does it mean you should? Sweeping between New York, London, and the Scottish Highlands, this is an extraordinary novel about unrequited love and unearned power.
