The Chiron Group acquired many of the titles previously published by Koa Books. Koa Books was founded by Arnie Kotler, whose considerable experience as a publisher started with his founding of Parallax Press, the publisher of Thich Nhat Hanh and other Buddhist teachers. After moving to Hawaii, Arnie began publishing books under the new imprint of Koa Books. In addition to Inner Gold: Understanding Psychological Projection by the beloved and renowned Jungian Analyst, Robert Johnson, Koa Books published books by many authors with a peace and social justice mission.
The Chiron Group entered into discussions with Koa Books in the second half of 2015 and began publishing titles under the Koa imprint in 2016. In addition to keeping Koa's classic titles in print, Koa will continue publishing books that seek to change the world. With authors like Jerry Mander, Lama Surya Das, Margaret Trost, Cindy Sheehan, Maxine Hong Kingston, and Sulak Sivaraksa, new authors who are making a difference in this world will be joining an esteemed group.
