Awen Alone has a definite Celtic focus but it is not exclusionary. The book mentions at several points that people of non-Celtic background should not be afraid to explore this path and that it is natural for druids to explore other pantheons beyond the Celtic pantheon.
Awen Alone offers a straightforward description of modern druidry. The author Joanna van der Hoeven explains without obfuscation the differences between joining groups and taking on a solitary practice. She makes clear that druidry can be a practice for atheists as well as a spiritual path and she assuages common fears about doing it wrong. The book also includes a particularly helpful and non-judgmental section with straight talk about different perceptions of gods and goddesses.
Where the beginning of the book emphasizes an openness to different ways of following a druid path, later in the book the tone becomes at times heavy-handed with an insistence that daily walks are the primary way to observe changes in nature through the seasons.
There are chapters outlining basic concepts of meditation, inner path working, and prayer. The author places a significant emphasis on connecting with ancestors of blood, place and path. The focus seems to be on a very flexible druid path. If there are any rules on this path, they are about respect and care for the natural environment. The only thing that is non-negotiable to the author is that you must explore your local environment and care for it, no matter what it is, urban or rural.
A loose version of the wheel of the year with Neopagan names for the feast days is promoted with the caveat that many people will adapt the dates to fit local climactic conditions.
The path of druidry presented here is attractive to eclectic Pagans. It may appeal to people of various backgrounds who have felt a pull toward Native American spirituality but don't want to appropriate the beliefs of that culture if it is not their own. The solitary druid path as presented here allows the individual to adapt an earth-centered spirituality to local conditions and to choose from a range of techniques such as various types of meditation, prayer, nature observation and inner path working to gain spiritual insight.
