As the IPMA agents concentrate their efforts in Maple Springs following the events in Troll Brother 1 & 2 and other stories, an unlikely group of allies discovers something hidden in the peaks of the Rocky Mountains. The question is who put it there and to what purpose? Will the short term truce between species of faerie and humans be enough to stop something catastrophic in the future?

It is not necessary to read the IPMA Troll Brother Extras to prepare for the re-release of Troll Brother 2 and the releases of Troll Brothers 3 and 4 in 2020, but they'll certainly add to the back story.
