Query Letter for my book - Non-Fiction

The book is about Silicon Valley and its industrial history. I am a first-time author and I need help with writing a query letter to send to the publishers. Here is more about the book- it is called "Silicon Valley Signals: Technological Enthusiasm & the Times." --------------------------- How might we account for the effectiveness of Silicon Valley during our times? Both as a place and as a cultural icon, Silicon Valley has generated a mystique about its power to produce economic and cultural effects. It speaks loudly in our civilization today and there is an aura of mystery about it. How has Silicon Valley arrived at this point in its development? Companies such as Apple, Google, Hewlett Packard,, and Intel compose part of the legend that Silicon Valley has become but the roots of that legend extend further in time and geography. Others have approached the same questions and have noted its industrial roots but only reached so far back. My contention is the modern economic and cultural phenomenon of Silicon Valley crystallized because of its local geomorphology and the ensuing technological enthusiasm contributed to its historical and material conditions for such techno mediatic unfolding. This work will distinguish itself from others not just by connecting geography to technical developments, but also by exploring the epistemological disposition that Silicon Valley claimed and spilled over into upcoming milieus of technological development and civilizational progress. By addressing the research questions through methods and concepts derived from Media Archeology methodology, a methodology originating in the field of Media Studies, I argue that the manifold inter-involvements of geomorphology and technical enthusiasm account for the force of Silicon Valley in media history, and the book takes you through various intersections of concrete pillars to build you a sound frame of mind about this mysterious region and culture.
