Continuing the storyline from Freedom's Landing, this second book in the series finds the human and aliens on the penal planet Botany planning a rebellion against their slavemasters. After the Catteni subdue and transport to penal colony planets people from Earth and other civilizations for their Eosi masters, one Catteni, Zainal, chooses to remain on Botany. His plan? To join his fellow slaves in convincing the absentee owners of the planet to turn against the Eosi and free the colonists. McCaffrey is at her best with interspecies interactions and uniting for a goal against a common enemy.

Freedom's Challenge by Anne McCaffrey

Abandoned on the planet Botany by their Catteni masters, a group of humans and other enslaved races now seeks to reclaim their worlds for themselves. This third installment of a series that includes Freedom's Landing  and Freedom's Choice  chronicles the stages of the war for liberation, from the theft of Catteni ships to the liberation of cargoes of slave laborers to a bold strike at the heart of the oppressor. McCaffrey excels as a storyteller and as a creator of worlds.
