The seventh book in the Transylvania Series by Radu Cinamar hails the return of Elinor, the mysterious and magical alchemist who introduced the author to a whole new world that led him to Tibet and to the recovery of an ancient sacred parchment. Re-entering the fold for the first time in many years, Elinor chooses to help Radu with an ambitious project that is not only designed to radically increase Radu's mental and visual acuity but which is also calculated to augment and transmute the consciousness of humanity itself towards a higher state of being. In the Etheric Crystal, Radu is pooling all of his many resources and the ancient art of alchemy in pursuit of the Philosopher's Stone so as to facilitate a mass awakening for Mankind.
