Most composers of the Romantic era had pretty interesting lives and Schumann is no exception. I really liked the biographical details in this book, such as his battle to marry Clara, his Florestan and Eusebius personalities, and his longtime struggle with mental illness. The author is also very careful and tries to avoid making any assumptions (ie. not insinuating anything went on with Brahms and Clara). There were also lots of great insights into his relationship with literature and how this affected his music. He also covers mostly all of Schumann's works even the lesser known ones. However, I'm also not into harmony, so I found myself skimming/skipping over the long frequent analytical passages.
I also didn't like the ending with the author commenting on the students listening to their dumb "fortunately not too loud!" rock music. He's trying to be like Schumann through glorifying the past, being critical of the present, and being hopeful for a "new poetic age" in the future, but unlike Schumann, he just seems pretentious. But other than that this is a really exhaustive biography that I would recommend for anyone intrigued in Robert Schumann!
