Esther Venrooy, a marvelous musician/thinker who doesn't release nearly enough work (!!) has written a book that charts her own development and discoveries, offering excellent and deep observations along the way. Beautifully written, closely and honestly reported, it's a really great document on a musician working in adjacent areas (improv, field recording, sound art) from the 90s until the present day. Highly recommended (as is Esther's music)
