Foreigner

Humans stranded on an alien world. Accepted by the aliens, until suddenly it was war. Because when the aliens are hard-wired in their brains to not even be able to understand the concept of friend; and loyalty to your boss is unbending and forever, until you realize a higher boss has pulled you away -- and that's not betrayal just natural, well, then, how can humans possibly interact? So, now, one man, Bren, is the sole interpretor for all human-alien interactions... and then the whole dynamic changes. A fascinating insight into what it really means to discover an "alien" culture. Gripping story that sets off a series now more than 13 titles strong.
