You may be interested in The Moonchild of Yesod: A Grimoire of Occult Hyperchemistry, or Typhonian Sex Magick by Karl Stone which is to be published around Lughnasadh 2012 in a limited edition of 418. Turns out this is the first title from The Imaginary Book Co. which appears to be based in the UK, though they don’t mention that on the site.

At €81 that’s about US$ 100, so there’s quite a premium on this book which binding seems pretty standard for a hardcover and I’m not sure why the price is so dear. But, it’s being given quite a send up by the publisher.
“Very rarely does a genuinely original occult book appear: this work, The Moonchild of Yesod (subtitled ‘A Grimoire of Occult Hyperchemistry, or Typhonian Sex Magick’), is just such a book. With an extraordinary use of language, the author builds on the work of Mme. Blavatsky, Aleister Crowley, and Kenneth Grant to construct a Magickal Mirror that opens a genuine Gateway to Beyond.” [via]
And I’m not sure what to say about the cover blurb, except … no, I’ll just quote it without comment. You decide for yourself.
“Oracular gnosis, is the hypostatic precipitation of phantasma within the non-spatial stellar dimensions of the initiate. Traffick with praeter-human intelligences are received as a concussion of ‘shadow signatures’ which colour (Kalas) the magickal mirror experientially as a Somatonoësis.
Magickally, the crystallisation of this phantasma is a Lunar sexual operation. It occurs within the oneiric womb of Yesod, which receives the praeter-human spermatozoon via the lens of Daäth (The gateway to the ‘Outer Ones’). Within this siderialised amnion, the spectral tinctures undergo a form of hyper-chemistry, whereby the colours (Kalas) out of space arouse a convolvulus within the ‘Astral Light’, manifesting an antheridial embryonate, the Moonchild (Homunculus), which consolidates it’s prescience upon the substrate of the terrestrial sphere. The Moonchild is the vehicle of the Magickal Will i.e. making the word, flesh.
This grimoire is both a Theoretical and Practical exegesis of initiation, sexual magick, qabalah and sorcery. It elucidates the tangential and oblique method, whereby contact with the subtle occult forces are amplified from the deep soundless recesses of non-spatial stellar loci as a physicality (Somatonoësis). Such transmissions are approached indirectly and inferred by the magickal engine of the qabalah, whereby their gateways are represented as tauroid gestalts (Sephira) to the ‘Outer Ones’. Such traffick can be used for mystical or magickal operations depending upon how the practitioner utilises these subtle intrusions (Kalas) of phantasma inspissated within the alembic of the adepts occult anatomy as a Somatonoësis.” [via]
