Resurgence (Unseen Things, #11) / Unseen Things (ePub)

The nathalis plan to wipe out the zethichtalarin was mostly successful, but a large number of zeths managed to escape to other dimensions before their worlds were destroyed. It was assumed that the threat had been eliminated, but assumptions can often be wrong.

After what was assumed to be a free army, led by a general with advanced tactical knowledge swept across the continent in the Faranox dimension, it was assumed that they'd done it to free all the slaves, and to wipe out the practice of slavery on the continent once and for all. Rather than releasing all the slaves however, they marched them back with them to the village where the army had formed. Why would a free army not just send the slaves back home, and where had this mysterious general come from that had the knowledge to lead his army to such a sweeping victory? The more the team in Washington thought about it, there was only one conclusion they could possibly reach. The zeths were back, and they were trying to build themselves a new home to use as a base of operations in the Faranox dimension.

Assembling a team made up of members of both the Washington and Scotland teams, as well as a newly human Thayelle, and a couple of ach'len who are hell-bent on revenge, the team heads out to the East Coast to begin their search. All the anecdotal evidence they've been able to gather so far has indicated that the mysterious free army originated from there somewhere, but with a lot of land to cover, the team has to disguise themselves as locals so they can gather information without raising any suspicions.

Back at home, a frustrated Jan discovers a new ability that will aid them all greatly on their mission. When the team takes that ability and comes up with some even more creative ways to use it, they suddenly find that they're all far more powerful than they'd ever imagined.

Resurgence is book 11 of the Unseen Things series.
