Citadel: First Colony. Citadel, #1

Crashing is the easy part. Book One of the Citadel SeriesIt'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, empowering the wealthy while burdening 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. "I opened one of [Kevin Tumlinson's] novels and immediately was hooked. I mean, he knows what he's doing.
