I came across ED when I was an angstful teenager, and loved her for the fact she could say in three and a half lines whatever profound thing I had recently come to realise. As I grew older I noticed her poems came with me - now she was taking to task the earlier self absorption, mocking it but saying new things that were profound in their turn. In the thirty years since, I've loved her poems for the fact they point to so many aspects of life we experience but don't always find voiced, or because she voices more familiar moments with originality, brevity, or style.
If you don't know her poems then a first glance might find them off-putting - there are so many, they are numbered not named, they are impossible to read in a straight line because of all the hyphens. But don't be put off by these things. They are not just not a major problem, once you 'get your eye in' they are actually good points! For example, she fits, by virtue of those initially - irritating - hyphens - things that ordinary sentences can't (like meaning several things at once). The huge number of poems mean she covers a huge range of life's moments, the numbers instead of titles mean come to them without any preconceptions of what they are about.
Her complete works are like a kind of journey, so wide ranging and varied that there is something for every person you are likely to be. Suitable (and comforting, thought provoking, satisfying) for reflective humans of every age, not just the teenage.
