Slice of Glory. The Glory Series, #1

Rescued from a burning building and pulled from the brink of death, four teens awaken at the threshold of a realm beyond their understanding-where they are given a mission that will change the fate of an entire world. Chosen to fulfill an ancient prophecy, they are sent into a hidden society no larger than a grain of rice, trapped beneath the rule of a ruthless emperor whose iron grip has crushed all hope of freedom.
In this miniature world, even the smallest step is dangerous, and survival depends on courage, trust, and faith in one another. Finding refuge among a secretive tribe of cave dwellers, the teens begin to learn the truth about the world they've entered-but their arrival does not go unnoticed. When two of them are captured and sold into slavery, the remaining pair must risk everything to find allies, master new abilities, and lead a daring rescue.
As rebellion stirs, a child is born-one destined to change everything. With evil determined to destroy this fragile hope, the teens must unite to save their friends, protect the child, and challenge a tyrant who believes himself unstoppable. An epic teen fantasy of prophecy, sacrifice, and the battle between light and darkness, this allegorical adventure asks what it truly means to be chosen-and what it costs to stand for hope.
