According to a Wall Street Journal review, Sorensen says, for the first time, that he "did a first draft of most chapters," "helped choose the words of many of its sentences" and likely "privately boasted or indirectly hinted that I had written much of the book."
Sorensen also admits that in 1957 -- just after the book won a Pulitizer Prize -- that Kennedy "unexpectedly and generously offered, and I happily accepted, a sum" for Sorensen's work on the book.
The overall review of Sorensen's book is glowing: "The heroic effort it required to complete this volume in the wake of his stroke, and to do so in a style that remains masterly, is itself an inspiration. Even when he is describing 40 years of post-White House law practice, there is hardly a page that does not confirm our sense of Mr. Sorensen as a writer of the first rank. If his active service to Kennedy is now concluded, we are still left with the inescapable sense that the words that the two men crafted together -- however one divides the credit -- will live on."
