Environmental scientist Dr. Johan Eschbach and his wife, the
world-famous diva Llysette, travel to Romanov-ruled Russia for a
cultural exchange and to investigate rumors of a deadly new technology
controlled by the Russians. Modesitt's latest addition to the "Ghost"
series (Of Tangible Ghosts, The Ghost of the Revelator) exhibits the
author's graceful storytelling and unique vision. Fans of alternate
history should enjoy this tale of deception and intrigue. A fitting
addition for most sf collections. -- Library Journal
