I found this book thoroughly engaging and read from cover to cover in a day. For a relatively short novel, its characters are deep and carefully painted, and so individual that by the end of the book it is easy to tell which character is speaking just by their dialogue. I finished "A Wreath of Roses" wanting to know each character's future. The descriptions are beautifully unique, and the book has a clever symmetry of events; its plot-lines are skillfully woven together from the start, with each choice a character makes affecting later events. It is not a cheerful read, however, but thought-provoking, giving rather bitter and cynical insights into human nature, the social/ gender roles of the 1940s, and fate itself. Helen Dunmore calls it "Taylor's darkest novel". I'd suggest it's best to read "A Wreath of Roses" if you're already a little acquainted with Taylor's fiction, or even the work of Elizabeth Bowen, which strikes me as similar.
It's also a great book to read if you're trying to improve your own writing: a lot can be learned from Taylor's use of description, dialogue and character.
