Tulpas

Inception meets Westworld in an original SF novel about a parallel universe only a dream away. In Tibetan Buddhism, tulpas are human-like creatures created through deep meditation. In this compelling story, tulpas take over the sub-conscious world in a parallel universe-where they quickly become invincible. For Bruce Lang and Risa Ferraro, on this side of that dream world, the tulpa army is just a puzzling nightmare.
But for their counterparts on the other side, Alex Brooks and Lydia Cabrera, the tulpa army-Dominion-is far too real. As the states of reality and dreams converge in an inevitable clash that may destroy all consciousness in both universes, the four must band together to save what is left of reality.
