Gabriel Blackstone, a genius with a computer and a thief of information, struggles with a request by an old love to find her husband's missing son. She asks him to use his unique talent of "remote viewing," a gift few have of entering a mind and seeing through their eyes. It's also a talent he's promised himself to never use again. But that promise is broken when he decides to venture into yet another mind.

With a little investigative work, Gabriel finds himself in the company of two beautiful women, Minnaloushe and Morrighan Monk, who are extremely skilled in alchemy and have a fascination with the art of memory. He needs to get close to them to hack into their computer and find any clues as to the whereabouts of Robert, the missing son. Gabriel works his way into the women's lives and discovers there's more to them than he ever thought possible. He must be careful, or he'll lose himself in the house with a million doors, otherwise known as the Promethean Key.

Natasha Mostert's unique creativity is spellbinding. She's able to expand on a theory of mind reading and takes the reader to heights unknown. This novel is absolutely fascinating and an invigorating read.
