What if; it is the core of the story writer’s journey of imagination. In Paul McAuley’s Cowboy Angels we look at our history with a new lens. What if a way had been found to move between quantum states, various versions of the universe we know. Similar in so many ways, yet different in so many others.
This is the what if that confronts the reader. I found the concept and the execution by the author to be first class. It kept my interest, my thinking and my enjoyment going throughout the story arc.
