For over 100 years 'The Poincaré Conjecture' was one of the most confounding puzzles. Invented by a French mathematician it was a theory that had the potential to describe the shape of the universe. It remained unproved and in 2000 the Clay Mathematics Institute identified it as one of the seven great conundrums of the new millennium.

Acclaimed literary biographer Benita Eisler sheds new light on the many roles, triumphs, and losses that together constituted Sand's overwhelming presence. The author of nearly ninety novels, twenty-thousand letters and thousands of pages of autobiographical writings and political commentary, how did Sand also have the time to live? As Eisler reveals, hers seems like several lives - literary, political, amorous, and domestic. Earlier biographers have either cast Sand as a feminist icon or blurred her in the dynamic of "child of the century." Naked in the Marketplace captures Sand's essence - the outsized public persona and the inner woman, along with the unique and irreplaceable role she played in the history of her times.

In this fascinating portrait of Darwin’s granddaughter, a key figure in the artistic and intellectual worlds of Cambridge and Bloomsbury, Frances Spalding creates a moving portrait of Gwen’s character, life and art.

In the years between 1714 and 1724, Jonathan Swift published little. This hiatus in his work is often dismissed as a consequence of personal disillusionment, and studies of Swift commonly move from 1714 to 1724 with barely a mention of his activities in that decade. This examination demonstrates a consistency of purpose on Swift's part, and uses his continuous dedication to the preservation and promotion of the privileges of the Church of Ireland to examine that fissure within contemporary Irish society. The unpublished, overlooked, and otherwise neglected writings of Swift, studied in the light of contemporary political and economic events in England and Ireland, reveal a politically astute observer and wise, if wary, commentator on events.
