Rav Simcha Kook was a voice of fire — and a heart of compassion.

From the historic alleyways of Yerushalayim’s Old City to the Chief Rabbinate of Rechovot, Rav Kook lived a life of courage, principle, and burning connection to Hashem. He rebuilt broken souls. He raised Torah institutions. He transformed Rechovot’s kashrus system into one of the most respected in Israel — setting a standard of halachah and integrity that reverberated throughout the country.

In this powerful biography, popular author Gedalia Guttentag brings readers into the world of a rav who never wavered. Whether facing courtroom battles, guiding baalei teshuvah, or quietly weeping before his private aron kodesh, Rav Simcha’s mission was always clear: serve Hashem and uplift His people.
