What can I say? This is my favourite book. I've read it over and over and have never tired of it. The characters are very real, and very relatable. The hero, Barney Snaith, is one of Lucy's most believable heros. Valancy is by far her most believable heroine. Everything just seems to click with this book. The chemistry of Valancy and Barney, the hilarious descriptions of Valancy's clan, everything. It's different from many of her other works in that love is not this instantanious thing between Barney and Valancy, where at first sight they are smitten with each other. It takes awhile to grab Valancy, and much longer still for Barney to realise his feelings for her.
Of course, the romance isn't the only reason why this book is great. It's also great because of all of the things Valancy overcomes and triumphs, such as fear, predjudice, etc. I find myself cheering her on every time I read it.
I would also agree with another reviewer who stated that he/she wished "The Blue Castle" to become a movie. I've thought that for some time now. Provided it was done well, I really think it would be great and would allow more of the country to experience what I believe to be L.M. Montgomery's greatest work.
