August Fortress (Kilenya Series, 3)

Since Jacob Clark discovered his abilities, his life has changed for the better--and the worse. The basketball coach won't notice him and high school is much more complicated than before. Jacob finds himself needed more and more in Eklaron where his abilities are saving lives. And then the call comes--he and his friends must rescue the powerful Sheingols from August Fortress where they've been held for fifteen years. The only problem is, Lorkon traps are everywhere and getting past them might be impossible. The closer he gets to his goal, the harder the traps are to overcome. Can he master more of his powers to fight the traps? Or has Jacob finally met his match?
