There is a new abridgement of the Secret Doctrine out by Michael Gomes, and published by Penguin Paperbacks in paperback and ebook, both at $17.95 US. (288pp.) It is good to see a major publisher have a Blavatsky book out. Gomes has a good intuition in his historical papers, so I imagine it is a good selection. There are probably many abridgements of the SD, the only I know of are, One edited by Elizabeth Preston and Christmas Humphreys for Quest Books and Theosophical Publishing house (260pp, $12.00), and another by Katherine Hillard, way back about 1900.
