The host - Stephenie Meyer

Melanic Stuyder refuses to fade away: The carth has been invaded by a species that takes over the minds of their human hosts, and most of humanity has suceumbed,

Wanderer, the invading 'soul' who has been given Melanie's body, knew about the challenges of living inside a human: the overwhelming emotions, the too-vivid memories. But she did not expect that Melanie would refuse to relinquish possession of her mind.

Melanie fills Wanderer's thoughts with visions of the man she loves - Jared, a human who still lives in hiding.

Unable to separate herself from her body's desires, Wanderer yearns for a man she's never met. As outside forces make Wanderer and Melanie unwilling allies, they set off to search for the man they both love.
