When it comes to action and adventure, every hero needs a good sidekick. Holmes has Watson, Batman has Robin, and Daniel has . . . Orrin. More like brothers than friends, they always have each other's backs. And as Daniel is the big, strong, handsome type, Orrin is more than happy to remain in his shadow at school, at parties, pretty much everywhere. Then things take a turn for the truly weird when a terrible accident catapults the pair into a world totally unlike their own, in which the rules of a role-playing game hold sway.

Due to unusual circumstances, Randidly starts in an isolated dungeon far beyond his level, forced to rely on the mysterious Traveler Shal in order to learn and survive with the dangerous new status quo for his world. But survive he does, only to leave the dungeon and discover that while he experienced several hellish months in the dungeon, only half a day passed on Earth. Randidly's capabilities are now more than enough to help build a small enclave of survivors, but that doesn't mean balancing his sense of responsibility against the plots of an unfriendly town will be easy.

A world on the precipice of the apocalypse. A secret forged in the flames of war. A chance to start over. For John Sutton, only one of those three things matters.

He’s been given a small farm on the outskirts of the empire as a thanks for his service, but no matter how far he travels, it's impossible to escape the war's devastating effects on the world.

Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since.

Tilling a field by hand is fun when you’ve got the strength of ten men—though maybe I shouldn’t have fed those Spirit Herbs to my pet rooster.

The question is: how?

Twenty-seven years is a long time unless you are trying to save the world. Nick was enjoying a late fall day, happily skipping his English class, when he was interrupted by a little silver ball. A ball that not only spoke, but claimed to be an alien artificial intelligence sent to warn humanity that a xenophobic alien race was on its way to wipe out every man, woman, and child on the Earth. The catch: They would arrive in 27 years.
