I can't find out anything more about this guy with Google. His author blurb on Wipf & Stock doesn't give me much confidence in his biblical studies training.
Twenty-four years ago, Preston Kavanagh retired from an executive position in a large company in order to seek the identities of those who wrote the Hebrew Bible. The Shaphan Group discusses what he found, as do his two prior books—Secrets of the Jewish Exile (2005) and The Exilic Code (Pickwick Publications, 2009). He and his wife, Lois, live quietly in Maryland.
Preston Kavanagh holds degrees from Princeton and Harvard. He retired twenty-five years ago from an executive position in a large company to seek the identities of those who wrote the Hebrew Bible. Huldah discusses what he has found, as do several prior books, including The Exilic Code (Pickwick Publications, 2009) and The Shaphan Group (Pickwick, 2011). He and his wife, Lois, live quietly in Maryland.
Huldah: The Prophet Who Wrote Hebrew Scripture reveals—for the first time ever—the extraordinary impact of Huldah the prophet on our Bible.
Huldah was both a leader of exilic Jews and a principal author of Hebrew Scripture. She penned the Shema—the ardent, prayerful praise that millions of worshipers repeat twice daily. Moreover, Jesus quoted as his own last words the ones that Huldah had written centuries before—“Into your hand I commit my spirit.” Huldah was an extraordinary writer—arguably she ranks among the best in Hebrew Scripture. As such, she added to God’s Word a feminine aspect that has inspired numberless believers—men and women alike.
This book’s new techniques reveal that though subjected to extreme verbal abuse, Huldah surmounted her era’s high barriers to women. As elder, queen mother, and war leader during the sixth century BCE, she helped to shape Israel’s history. And what, then, can this book mean to scholars—both women and men? Feminists need a rallying point and a heroine, and Huldah makes a superb one. In years ahead, experts might well place Huldah alongside the very greatest women of antiquity; indeed, they may even conclude that she is among the most influential people in human history.
