Against Her Nature — Elizabeth Buchan

In the late-80s, Unlike the Frants living their quiet ordered lives in the village of Appleford, Tess and Becky are of the generation that reckons it can have everything. They are negotiating the world of high finance and the City. High flyers in the high-octane world of London's high-finance, they move through the opportunists, the short-termists, the sharks, the bullies and the very, very rich. When disaster hits amid rumours of incompetence, Tess's father, a Lloyd's Name, suffers terrible losses. Meanwhile, Tess and Becky are faced with hard choices, not least the one presented by biology: children.
