O romance é "Diplomatic Act", de Peter Jurasik & William H. Keith Jr. copyright 1998.
Richard Faraday didn't believe in aliens, even though he played one on TV. Unfortunately, the aliens believe in him ... or rather, they believe in Harmon, the alien diplomat Faraday plays on the SF program Star Peace. A war is threatening to tear the civilized galaxy apart, and only a diplomat as superb as Harmon can stop it. The problem is that the real aliens are just a little confused about the bizarre human concept known as fiction. They think Harmon is real....Well, real or not, "Harmon" had better solve their alien problems fast or Faraday, galactic civilization and Earth itself will be abruptly canceled.
Um bom romance que é muito semelhante e lançado um ano antes do romance / filme Galaxy Quest.
