When I Walked Among Serpents - Yellow World, #3

He was a large yellow man in a green world. When pirates disable his interstellar transport, Lonin, the first Timmistrian ambassador to the Co-Operative League of Systems, is forced to abandon ship in an escape pod. Now alone and lost on an unfamiliar human world, he is captured by traffickers and thrust into an international war that threatens the stability of the entire planet - and any chance of escape.
With only his untested diplomatic skills and the timeril sense that allows him to see the nature of other people, can he find his fellow travelers and gain their safe passage to their intended destination, the Co-Op capital of Smyth Alter?Only an entire world of hostile people stand in his way. And the dreaded alien Thinkers, killers of human worlds, are coming.
