My friend Rabbi Pini Dunner recently published a fascinating book, Mavericks, Mystics & False Messiahs. This slim and mesmerizing volume discusses a variety of colorful episodes from Jewish history. Some of them are well-known stories of considerable significance, such as Shabbtai Zvi, and the fight between Rav Yaakov Emden and Rav Yonasan Eybeschutz. Others are lesser-known stories of mavericks, such as Samuel Falk and Lord George Gordon. The book is not intended as an academic work, but rather as a popularization of accounts that are usually only known by history buffs.
