This biography is not for Hemingway beginners, and I'm glad I read it after some others. This wasn't planned - I just happened to find Michael Reynolds' books first. I don't mean that to sound condescending. What I mean is that if Lynn's book is the first or only one you read about him it might mess with your perceptions of the great writer too much.
It's like looking at only one face of a many-sided and varied object. You need to see more of the different sides to really understand the whole (or begin to).
For newly infatuated Hemingway lovers it will undoubtedly leave a bad taste in your mouth to see him with so many of his flaws and hangups laid out, and may even cause you to forget why you liked him at all.
Or, for those inclined to look for it, this book might merely confirm what you knew all along, that he was at base a difficult, even vicious person, someone completely defined by sexuality struggles and alcoholism.
That the book attempts to explain and understand the dark sides of Hemingway's personality doesn't mean we have to view the author solely in this light, however, just like we shouldn't be required to see him only as a romantic figure, some heroic example of masculinity.
When it comes to "great" people, those who have led what we might call extraordinary or outsized lives, maybe we feel a stronger desire to study their makeup, to better see how they did what they did.
For me Hemingway was many things, some good, some bad, and Lynn's book uses a psychological focus to look into what may have been behind the "bad." That's what it's mainly about. I think it's an important contribution to an overall understanding. It doesn't - it can't - explain every last thing about him.
The reason we are so fascinated with him, the simple and basic reason, is the same one for all geniuses - we are awed by his amazing gifts. That can't really be explained; it just is. What he did with his artistic talent and how he managed his life in light of it is to me the real story, and Lynn's book is definitely an interesting chapter.
For recent initiates to Hemingway biographies, like I was a few years ago, a great first or early read is Reynolds' Hemingway in Paris. It gives you all of the good stuff about his life over there and his development as a writer. The excitement of what he was beginning to achieve is matched by the romantic setting, the trips around Europe, and the social interactions within his new circle. Like always with Hemingway, it was as if he was writing his own life, and this was a really fun part.
The book also shows the flaws and darker things about him that were always there. It's especially devastating when he leaves Hadley after finding some success. That decision marked the end of the "good" times in Paris and apparently haunted him, as he hints at the end of his life in A Moveable Feast.
