Jan Palmer has everything—except happiness. He wishes to escape to another world. But be careful what you wish for.... Waking out of a deep sleep, he escapes—into a living nightmare. In a realm of deadly secrets and dangerous dancing girls, he discovers that humankind’s fate lies in his hands. Abounding in revelation, this is a tale that might just open your eyes. “I stayed up all night finishing it. The yarn scintillated.” —Ray Bradbury
