Elder Race, by Adrian Tchaikovsky

Fantastic short book, told in two perspectives. Lynesse Fourth Daughter is a fantasy princess, climbing the mountain to the mystical tower to request the aid of the immortal wizard Nyrgoth. Nyr is an anthropologist from Earth, dropping in and out of suspended animation to track the culture of this post-tech colony world. The two protagonists and how they see and deal with each other are beautifully written and the translations between what he wants to say and what she hears is great. Also a fine adventure tale.
