The Ivory Mask

When Thea Alexander begins to have strange dreams of a place and time very unlike her own, she doesn't realize that she is about to be caught up in world-spanning intrigue. The dreams show her the world and the life of Thehath (whose name means 'inscrutable'). He is the Personal Translator to the Emperor of the Hidden Kingdom, a crucial role, since the Hidden Kingdom is playing host to emissaries from an impossibly distant and hitherto unknown land who say they are seeking trade and collaboration, but whose actual mission is secret and far more sinister. What Thea doesn't know is that Thehath is dreaming her dreams, and the two of them are destined to become the agents of a beneficent goddess, bent on protecting both worlds from the machinations of the strangers from a distant land. When Thea and Thehath wake up in each other's bodies, each of them has to negotiate the strangeness of the other world, as well as determine how best to guide events in order to thwart their enemies and save both worlds from disaster.

A rich cast of characters, skilled world-building, compelling plot twists, and enthralling intrigue make this stand-alone fantasy novel one not to be missed.
