I’m going by the previous bios...Twain, the Roosevelts...all terrific.
The WSJ already has a piece up about the bio, pointing out what they plainly see as Hemingway’s bluster, bullying, braggadocio, etc. etc.
The saving grace will be the presence of Tobias Wolfe, who judges Hemingway clearly, fairly and humbly, as a man and a writer who, as Wolfe says, moved all the furniture in the room, always and forever.
