Warhorse - Timothy Zahn The book revolves around two characters: Roman, who wants peace with the Tampies, and Ferrol, who is very much against. Both are assigned to the same mission, which may be the last chance of averting war with the Tampies.

What I like is that neither side is demonized and how Ferrol and Roman come to respect each other. A fairly good read that I got through in one sitting.
