It is very good to see reference and discussion of the early writing efforts of Hemingway. Other biographies give the impression that this early work no longer exists. However, this author over estimates the influence this early writing had in Hemingway's development; which was actually zero.
Reynolds writes in a novelistic fashion, which makes for a flowing read, but he inserts long passages of his assumptions, guesswork, and interpretation along with information from sources, presenting the whole as though it was fact. This misdirects and misinforms the reader.
Reynolds states Hemingway decided to change his persona to the Hemingway persona we are familiar when still a teen, declaring his own natural personality as "weak". This is overstating by far. He did not begin to create a persona until years later. Most other sources tell us that the Hemingway of his youth up to his mid or even late twenties was the same, genuine Hemingway. Further, that this person was largely likeable and extremely talented.
But Reynolds seems to suggest that creating the persona and trying to become it was a good idea and necessary for success, rather than the mistake that helped in his destruction as is accepted by all of the many biographers I have read so far. It is daring for Reynolds to state this view, but he does nothing to back it up, he just states it as a fact.
Hemingway does a great job of slagging the father, but the mother's well established extreme self-involvement, rigid judgmentalism, tendency to self dramatize, and insistence on controlling others, Reynolds dismisses as "exuberance". It is always fatal to an analysis when a biographer loses objectivity in this way.
There are many interesting facts about Oak Park and the family listed in this biography, but often Reynolds' research is sloppy and his editorial choices questionable. For example, Hemingway got his job with the Star though contacts, not from hanging around outside the office for days; WW1 Ace Billy Bishop was not "an American", he was a Canadian, even the most sloppy basic search would have revealed that fact; the letter of the Nurse Agnes to Hemingway is misrepresented in summary, the contents should have been quoted, whilst in other sections quotes from Oak Park newspapers are needlessly given in full; the relationship between Grace and Ruth Arnold is presented with unbelievable naivete; Hemingway's influences on his later style were more than Anderson and Stein
(and many biographers do not include Anderson). They also included Ezra Pound, Hemingway's newspaper experience, his music lessons from his mother, and study of the paintings of Cezanne (though perhaps Reynolds corrects this error in part two of his series on Hemingway).
Reynolds states that Hemingway always held to the Victorian moral codes that he was taught as a small child in Oak Park. This is not true, he changed as he lived through Kansas and Paris and the war, he changed as the world changed, he matured, he outgrew Oak Park and its narrow religiousity, and he had no desire to return, he in no way remained "a good Oak Parker". If he had, he would have lived permanently in Toronto, that "city of Churches" as Hemingway put it.
Reynolds proposes that Hemingway did not write about his home town. But whether he named it as such, Hemingway clearly wrote often about Horton Bay and the people of Oak Park, and set stories in those places. When they read the stories the Oak Park people recognized some of their neighbors, and themselves, as character models.
In another section, Reynolds insists that Hadley had no other romantic interest except from Hemingway. This is false. She had admirers before and after meeting Hemingway. This biography also states, oddly, that Hemingway never slept with a woman he did not want to marry, ignoring that at first he had no intention of divorcing Hadley and marrying Pauline. Reynolds then implies Hemingway slept with Kate Smith and Marjorie Bump. Ironically, other biographies argue he did have an affair with Jane Mason, and perhaps a very few others in Paris and the following years, and without any intention of marrying them, whilst it is only speculation that he had a romance with Kate, and there is no reason at all to think he had romantic relationships with Marjorie or any other Oak Park woman. The examples presented in the above few paragraphs are just a sampling of the book's sloppy research, poor editorial choices, and questionable analysis, and of course, to repeat, Reynolds prints his guesses and assumptions as facts.
There are better books written about Hemingway's early life, one need not bother with this except to read everything written about Hemingway. I have high expectations that Reynolds' next volume about Hemingway in Paris is much better than this first effort.
