Book 7: Rivals (Part 1)

A Power From The Ground thrusts Joe and his companions into their most explosive adventure yet. After bidding farewell to Raurui Village, the group sets out across plains and beaches—only to be ambushed by Gerald, a vengeful enemy with fire raging in his veins. What begins as a midnight attack erupts into a brutal showdown between Gerald’s infernos and Sora’s unrelenting waves, a battle that shakes land and sea alike. Just when defeat seems certain, Joe awakens to deliver a decisive strike that changes everything. But the true danger is only beginning. Days later, the travelers enter the Burning Forest, where desert sands conceal monstrous Savages—twisted humans hungry for blood. Their only hope lies in Rabe, a mysterious fighter with a tragic past and a vendetta that could either save them or doom them all. Packed with fierce battles, shocking revelations, and new allies, Book 7 takes the Thunder Learners deeper into darkness than ever before.
