It would be a mistake to think, at first glance, that this two-volume work is little more than the extended biography of a moderately well-known sixteenth-century author. Rather, it is a detailed and compelling history of the early Reformation in France through the prism of Marguerite of Navarre's life. As sister to Francis i, she was peculiarly well-placed to take a leading role in pushing the cause of the Reform at court. Reid demonstrates that her value as a patron and protector to the movement in France was invaluable, both in Paris and on her own provincial estates, and asserts that this role deserves due recognition as it was pivotal to the movement's fortunes. He carefully constructs his argument for placing Marguerite at the centre of a dynamic if hard-pressed group which sought and failed to establish a successful Reformation of the French Church under royal auspices. In this he is persuasive, deftly presenting an array of sources to reinforce his thesis. Indeed, half of volume ii consists of a meticulous listing of Marguerite's correspondence and the works produced by those in her network, to provide the most comprehensive compilation to date. Reid provides real insights into the not-always-harmonious relationships between individuals within the group, which included leading figures such as Jacques Lefèvre d'Etaples, Guillaume Farel, Gérard Roussel, Clément Marot and others, and their association with an international Reform movement. A careful balance between detailed discussion of the published and unpublished works of this network, alongside the political events and circumstances which largely determined its fate and Marguerite's framing of her role in religious terms, makes for a compelling picture. This is a scholarly work, fluently written and clearly organised, with extensive footnotes. In addition, the reader is immediately struck by its handsome presentation (volume 139 in Brill's Studies in Medieval and Reformation Traditions series), which does credit to the press as well as to the author. This in-depth study is a timely corrective to our understanding of the course of events of the early Reformation in France which has been largely neglected in recent scholarship. It is clearly positioned in relation to the traditional interpretations of the movement, questioning received notions about French religious anarchy and independence from developments elsewhere, whilst also emphasising Calvin's hostility to its members' apparent prevarication. Thus, Reid resurrects not only Marguerite's reputation, but that of all the participants in the movement, who battled against both Church and crown in an attempt to bring about reform without causing internal strife. The subsequent religious wars undid this hope, but a case is made for the moderates of the period, such as Bishop Jean de Monluc, as heirs to this pacific tradition and, thus, to Marguerite's legacy.
