A new world means a world of trouble... The Paragon Engine, a machine that can unlock portals to any dimension throughout the universe, is the most powerful and dangerous invention in Templar history-and the Grey Griffins have just been pulled through it. After they are transported through the engine, Max, Ernie, Natalia, and Harley have no idea what to expect. There could be vicious monsters or terrifying creatures lurking around every corner. But soon, they discover that this new world looks just like theirs. Except there is one big difference: everything that went wrong in their world never happened and the Templar rule society. Is this world truly perfect? Or should the Griffins risk their lives to find a way back home? Things get even more complicated when they learn that their arch enemy, Otto Von Strife, is also in this world-and he has the power to destroy everything. In this final book of the Clockwork Chroniclestrilogy, the Grey Griffins face questions about destiny, personal choice, and what courage really means-all while finding a way to destroy Von Strife, his evil half-fairies, and his legion of killer clockworks.
