Older, Wiser, Sadder?

Here's a heads-up to Anne of Green Gables fans! LM Montgomery's final book in the Anne series will be published for the first time in its entirety this fall. The book is set before and after the first world war, and uses short stories, poetry, and dialogue.

The book looks set to reveal a darker side to the author, with its publisher promising themes of "adultery, illegitimacy, misogyny, revenge, murder, despair, bitterness, hatred, and death – usually not the first terms associated with LM Montgomery". [from the Guardian story]

An abbreviated version was published in 1974.

I only read the first Anne and the Emily of New Moon trilogy, and didn't see any of the TV or film versions, so I'm not a die-hard fan. What do you guys think of this? If you are fans, will you read this?
