An Ancient Return - D K Holmberg - Bog

The key to saving the future may come from the past.
The Sul'toral have been defeated, but peace is always tenuous-especially around Yoran with the El'aras and Leier making it their home.
When Gavin discovers a strange change to the ancient bralinath trees that connect him to a deeper El'aras magic, his search for understanding leads him toward different type of foe than he's ever faced, only his power may not be enough to stop it. Worse-that very magic may be what his new enemy needs to succeed.
The fight is like nothing he's ever encountered, and to survive, Gavin needs to fully understand power he's never fully embraced.
Can he do it before everything he's gained is taken from him-and used to destroy him?
