Elsinor is an alien being who lives on Earth now, in our sixth dimension.

This book is about adventures with Elsinor and Adeline, two aliens whom I encountered, and Gwenllian ferch Llywelyn, the last Princess of Wales, who lived in the thirteenth century anno Domini, and the Indian Goddess Lakshmi, whom I met while exploring within the Twenty-third String.

Dr. Mayo's books are based on his personal Lucid Dreaming encounters.
