In its August 2020 edition, Publishers Weekly posted the following review of The Ukinhan Wilds:
Thompson (The Sundered Isle) kicks off his Warder series with this adrenaline-charged fantasy adventure. While searching for a passage at sea, rogue swordsman Kylac Kronus chances upon a promising quest when he rescues sailor Sallun from a traitorous band of Addaran Shadowguards. In exchange for saving his life, Sallun introduces Kylac to his crew, who were tasked with finding and safely returning the abducted Princess Denariel to her father. Their captain, Ledron, taps Kylac to serve as their mission’s defense against an intelligent mutant called the Ukinh. They rescue the princess with little fuss, but their long sea voyage back to her kingdom brings them first to treacherous waters, then through the Ukinhan Wilds, the “homeland to the mutants.” And when they finally arrive in Denariel’s home kingdom, Kylac realizes that there is more to the story of her abduction than first meets the eye. Though the plot is electrifying, Kylac himself remains an enigma, which will frustrate some readers. Still, Thompson’s dense, atmospheric worldbuilding and cinematic fight scenes will keep the pages turning. Fantasy fans won’t want to put this down.
