Bradford Angier (1910 - 1997) was a wilderness survivalist and the author of numerous bestselling books on nature, survival, and living off the land. His writing is supplemented by text from noted survivalist and naturalist writers including Gregory J. Davenport, Christopher Nyerges, Jon Young, and Tiffany Morgan.
When not writing his novels, Kyle Mills prefers to spend his leisure time climbing some of the most dangerous rock faces on earth; an experience he finds 'refreshing'. If the reader is daunted by such a prospect, highly satisfying surrogate thrills may be found in the pages of Mills's novels instead. His protagonist here is FBI agent Mark Beamon, a man who refuses to play by the rules. Preferring to tread on toes and say the unsayable has resulted in Mark being consigned to the CIA Siberia of the Phoenix branch. But then it is discovered that a group of terrorists in the US has gained control of missile technology, and Mark is set on their trail. And as other agents begin to die, he discovers that the tendrils of the terrorist group extend into some unexpected places. The theme here is not new, but in Mills's hands it's fresh and exciting. His own father worked for the Agency, and the author includes some extremely plausible spycraft detail. Mark is a complex and interestingly drawn hero, and though the plotting here may initially seem to be a little discursive, it quickly focuses into something powerful and involving. Mills never underlines the topicality of his theme, but Sphere of Influence is always firmly fixed in the dangerous world we live in. (Kirkus UK)
