Leila and her compatriots quietly hide from the Horde, trying to figure out what their next plan of action will be. When Leila goes out scouting and hunting, she encounters a Troll scout and immediately kills him. Knowing that the dead scout will result in more Trolls, Leila and the others decide it is time to move on. As Leila realizes that the Trolls are heading North, she guesses that this group is planning on flanking Ariel, the Ice Mistress. Leila and the others choose to get ahead of the Trolls to try and warn Ariel but Robyn decides to split from the group.
Robyn plans on heading South instead, to train and become a Shifter like the one she saved in the Horde encampment. They part ways and Robyn heads South as the others rush North. However, Robyn runs into a strangely desolate and dark forest to encounter an ancient creature that was thought to be extinct, the Treant. Robyn has quite an interesting experience with the Treant while Leila is surprised by a group of Trolls. Can Robyn charm the ancient beast and will Leila overcome the Trolls?
It is highly recommended though not required that the Realms of War Trilogy 1, 2 and 3 be read prior to reading the Realms of War 10.
