The purpose of genre is to give the customer some basic idea of the fiction or nonfiction category the book falls in. This makes it easier for them to find it on the bookshelf. From there it's usually the fight of the well-known author, or for that rare reader, inquisitive enough to traverse new territory, it might be the arresting cover, or the concise blurb inside the cover or on the back of the book. In the adult fiction category, there are your three basic genres: romance, mystery, and science fiction.
Science Fiction is primarily the genre of ideas. In Matt Browne's series The Perennial Project, his focus is on the movement of mankind to the stars. The first book, The Future Happens Twice explores the how and why we get to the stars. Why we go, is simply because to not do so, mankind will become extinct. Earth and the solar system can not last forever.
