Behind the scenes, this book took effort, research, and care to write meticulously accurate fact-based fiction. The places, the science, and the vocabulary are all thoughtful and engaging. The people, the story, and the effect are enjoyable. Unlike science fiction or time travel novels that follow a predictable structure, Walker writes a genuinely authentic story of a realistic protagonist with integrity, hope, good intentions, and the capability of growth. This is a feel-good book through and through. Even in the darkest moments, there is always a light to shine the way through it.
