Flesh by David Szalay

Once a shy young man from a town in Hungary, István is carried gradually upwards on the currents of the 21st century's tides of money and power, moving from the army to the company of London's super-rich, with his own competing impulses for love, intimacy, status and wealth winning him unimaginable riches, until they threaten to undo him completely. Spare and penetrating, 'Flesh' asks profound questions about what drives a life: what makes it worth living, and what breaks it.
