Cauldron (Academy – Book 6) 

‘A writer who is a storyteller first and a science fiction writer second. In his ability to absolutely rivet the reader, it seems to me that he is the logical heir to Isaac Asimov and Arthur C. Clarke’ Stephen King The year is 2255. The Academy that trained the starfarers is long gone and veteran pilot Priscilla ‘Hutch’ Hutchins spends her retirement supporting fund-raising efforts for The Prometheus Foundation, a privately funded organization devoted to deep space exploration. But when a young physicist unveils an efficient star drive capable of reaching the core of the galaxy, Hutch finds herself back in the deepest reaches of space, and on the verge of discovering the origins of the deadly Omega clouds that continue to haunt her.
