Citadel: First Colony

It’s been more than a century since humanity escaped the overpopulation of Earth, expanding out among the stars. We’ve faced and overcome war with an alien race. We’ve survived terrorist attacks meant to end colonization. We’ve thrived despite unregulated class distinctions, separating the wealthy from the working class.

What comes next may be the end of it all.

A lone colony of human castaways, led by a former alien enemy, find themselves at the mercy of a saboteur and a plot to end humanity’s unrestricted travel among the stars. This could be the finale of the colonies and the end of a species. Everything depends on how smart - and how forgiving - humanity can actually be.

- JoAnn Takasaki, Author of "Luau Like a Local: The Easy Way”

About Kevin Tumlinson

You know those guys who sit in Starbucks, sipping lattes from paper cups, tapping a toe to the overhead music, and occasionally (awkwardly) laughing aloud as they type away on their MacBook for hours? Kevin is that guy. Usually with a bow tie.

Kevin is a speculative fiction author who lives, works, and occasionally plays in the Greater Houston Area. He and his wife, Kara, enjoy "dream driving" in nicer neighborhoods than they can afford, bickering about where they'll live when they win a hypothetical lottery they never play. Until then, Kevin keeps doing what he loves -- and what he loves is telling stories in exchange for fistfuls of money. Buy his books.
