BUNKER TP (2025)

"As Grady Potts' political star rises, Daniel finally realizes what he must do to ensure he doesn't poison the world's population, and it isn't pretty. Natasha is on hand-actually, both Natashas are-but the consequences of his actions may change the future for the worse. Heidi is still imprisoned, but just like Billy, she's got an advocate on the outside. In this explosive final volume of the critically-acclaimed series, the fate of the world will be decided."

"The end of the world is in motion. Alliances have broken and reformed. And the motives of those who have come from the future remain unclear. Still, all the five friends can do is continue on. While Grady pursues his future in politics, Billy's stuck in jail, his future-again-uncertain. But when the older Grady drags Heidi into the fray, Billy decides to fight back."
