I read for how creatively authors demonstrate "plot is character is plot....". One of my foremost writing goals is to write and sell a story that encourages young and even middle age adults to read more to expand their awareness so they are better equipped to define their internal and external worlds. That's why I care about the higher concepts of story that can flow down and persistently infuse the story with needs, desires, and conflict. Coming of age is a worthy high concept when infused with the recognition of the evolving interaction we all have with our world. Coming of age is an ageless high concept that applies to all of us as we evolve to come to terms with the story of our lives' next chapter.
