When the interlopers invaded Earth, the System they brought with them offered everyone a choice: "Champion," "Soldier," or "Support." University student Xavier Collins picked "Champion" without reading the fine print — and now finds himself thrown into the extra-dimensional Tower of Champions, where every floor is deadlier than the last. Back home, an invasion he can't stop is already underway. Earth is running out of time. And so is he. Xavier's only shot at saving his world is to climb the tower as fast as he can. Every floor is a fight for his life. But every level up unlocks powers he could only dream of. Publisher - Aethon Books
