Spviack's portrayal of Lowell in particular, but the others as well, is both heartfelt and honest. Unlike an "official biographer" who is boringly objective in their depictions, she has no qualms about letting her affection for her subjects shine through or letting us know how much she admired somebody. However, she's not blind to their faults either and is unstinting in her honesty when listing them. At the same time she doesn't try to hide the fact these are her impressions of these people. She does give us indications of other people's impressions of them, Lowell especially, by including quotes from her contemporaries at the end of almost every chapter which address an aspect of their character.
While this book is by no means a definitive study of the work and lives of the poets you'll meet within its pages, it provides an even far more valuable service. It allows us the chance to look behind their reputations and the myths that have grown up around them to see them as the complex and interesting people they were. This book is probably the best introduction to the world of American poetry in the 1950s, 1960s and 1970s you're liable to read.
