Oblivion. The Wonderfall Series, #3

Some truths break you. Others remake you. Carter Simms is about to face both. After surviving the chaos of Hollowtown, Carter Simms knows the world is running out of time. The lies that shaped his life are unraveling, the truth is closing in, and a final challenge waits-one that will decide the fate of humanity itself. To face it, Carter must assemble a team of allies he trusts, fears, and barely understands.
Together, they step into a game unlike anything they've ever encountered. But the deeper they go, the more the world around them fractures. Secrets surface. Loyalties strain. Old wounds reopen. And Carter begins to realize that the people closest to him-friends, rivals, even those he loves-are carrying truths that could destroy everything they're fighting for. Worse, he carries a secret of his own, one that threatens to tear the team apart before the challenge even begins.
Their journey leads them toward a place whispered about in fear and buried in myth-a place known only as Oblivion. What waits there is older than the cities, deeper than the arenas, and more dangerous than any enemy Carter has faced. Within its walls lies the truth behind humanity's demise and the key to its survival. As the world tilts toward collapse, Carter must confront the forces that shaped him, the choices that define him, and the sacrifice that may be required of him.
Because in the end, saving humanity won't come from winning a game-it will come from facing the truth he's spent his entire life running from. And some truths demand everything.
