Empire of the One (Wine of the Gods Book 14) by
Pam Uphoff
I have read this (more than twice) and enjoyed it.
They crossed the dimensions to spy on the World that attacked their own. The "Oners" had been very high tech, very aggressive, as magic as their own people. They went to collect information, and found a world preparing for war. Can they use this strange world's social conventions to derail a war?
