Nathan and Phillip, with their symbiotes, strain to lead the Kashallan Alliance against their Ghostlander enemies. They must learn to trust native war magics as well as their own off-world technology, as all resources are needed to protect them in this struggle. And what can Tessa do if her human body is not strong enough for the fighting that her own inner Demon must win, to protect them all? Treacherous Campaign is the eighth book in the series Tales of the Kashallans, by celebrated author Celu Amberstone. Drawing on her Indigenous and Celtic heritage, Amberstone writes powerful fiction subtly different from the usual science fiction or fantasy adventures. For fans of the 'Hundred Worlds' approach used in Star Trek and in Golden Age magazines, there are diverse settings and cultures along the journey taken by these human and alien characters. "e;This is space opera writ large combined with both fantasy and hard SF... It's obvious the Tales of the Kashallans constitute a genuine epic written with such skill that you will be enthralled however long the series lasts."e;This is a richly detailed fantasy/space opera that is positively addictive. Celu Amberstone has the knack of weaving elaboration and action into a vivid tapestry of action and character. Well rounded, deftly written, and a joy to read. Highly recommended. Consider it a useful antidote to mundane life these days... a genuine pleasure you owe yourself."e;-R. Graeme Cameron for Amazing Stories. "e;Amberstone's world-building puts together brave new peoples and gritty adventures, evoking strong responses in the reader."e;- author Paula Johanson
