Many of our readers will already be familiar with the Texts and Studies of Reformation and Post-Reformation Thought series ably edited by Richard A. Muller. This is a valuable series that has contributed greatly to a better understanding and appreciation of the details of Reformation era theology and theologians and the profound riches of the Reformed Scholastic era as well.
The latest addition to this august series is Reformed Thought on Freedom: The Concept of Free Choice in Early Modern Reformed Theology. You can find the book here. Co-edited by Willem J. van Asselt, J. Martin Bac, and Roelf T. te Velde, the book has an excellent introduction explaining the recent growth in post-Reformation studies and the context of Reformed scholastic discussion of free choice.
The remainder of the book contains chapters of primary source material by Girolamo Zanchi, Franciscus Junius, Franciscus Gomarus, Gisbertus Voetius, Francis Turretin, and Bernardinus de Moor. These were theological heavyweights in their day and we are the poorer for not having read them. The book concludes with a helpful summary.
This is an excellent series and this volume in particular will add to our understanding of this contentious issue. My own experience with reading Reformed scholastics is that you come away amazed at the comprehensiveness of their treatment of a subject. One may not agree with them but one must reckon with their analysis.

I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
