The narrative resumes - at last! - in Book Six of My Struggle

After a 400-page digression, Karl Ove Knausgaard gets back to his narrative in Part 2 of My Struggle: Book Six (75% of the way through the novel), and I am pleased about that - and I assume most readers who even get this far will agree. To be honest I see no reason why that extensive digression is included in this book - so far his discussion of Hitler and various literary topics provides neither background, foreshadowing, nor any useful information that advances our understanding of sympathies as KOK continues with the final take on his life up to age 40. In this final movement of the novel, we are back to KOK w/ his wife, Linda, and their 3 young children, as he embarks for Oslo for the release of Book 1 of My Struggle, and we get further views of his extreme anxiety and doubt of his self-worth and his social awkwardness - traits that would not necessarily be evident to those who meet him casually or professionally. By all indications, his readings and media interviews went well; he doesn't feel that way though, he remains tormented and wracked w/ guilt - making it all the more amazing that this shy man should write 6 volumes recounting the most intimate and personal aspects of his life. A dark cloud hovers on the horizon as we near completion of this book; there's been a sense from the start of Book 6 that his seemingly happy marriage is on shaky ground, as KOK recognizes that Linda has not yet read the ms. of the so-far unpublished Book 2, which concerns the early years of their relationship. I think all readers have a sense that when she does read that manuscript - and of course we have read Book 2 and know about Linda's psychological troubles - the marriage will break apart. As approach that cliff, however, KOK takes a step back in time to an earlier point in their marriage - L is pregnant w/ their 3rd child at this point - as the foursome take a vacation in the Canary Islands - a package tour of the cheesiest type, and it's hard to believe they would sign up for such a jaunt, but there you go. They even are so naive as to fall for one of those stay at our beachfront for the day and all you have to do is listen to our sales pitch about a timeshare; KOK is so naive as to want to buy the timeshare on the spot; Linda has better sense than that. But we see the fissures in their marriage (as well as his financial irresponsibility and his impulsiveness) and this jaunt ends with an echo of the opening of the fateful Book 2: Everyone else but us seems to be having a good time. Is that accurate - or does "everyone else" also hold and hide secrets and terrors?
