The Host by Stephenie Meyer (author) (UK edition)

What if you refuse to let your body be taken over by another soul? What if you resist? Earth has been invaded by parasitic aliens who possess the bodies and minds of human hosts. Most of humanity has succumbed. But Melanie Stryker refuses to fade away. Wanderer, the invading ‘soul’ who has been given Melanie’s body, was warned of the challenges of living inside a human: the overwhelming emotions, the too-vivid memories. But there was one difficulty Wanderer didn’t expect: the body’s former tenant refusing to relinquish her thoughts. Melanie’s soul refuses to budge, flooding her possessor’s mind 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 on an epic search for the man they both love…

A chilling sci-fi romance exploring love, choices and possession by Stephenie Meyer, the globally bestselling author of Twilight.
