Bests & Worsts Reviews from Amazon

Is this a biography of Laura Ingalls Wilder or of her daughter, Rose Wilder Lane?? While the book does include Laura's story, the bulk of it seems to rant and rave about Rose. Clearly, some of Rose's background needs to be shared in order to explain the dynamics of writing the Little House series.... but really it comes across as a rant from the author, who clearly does not approve of Rose at all. This 509 page book could easily have been pared down to half that if it wasn't so verbose. Truly it reads as one long stream of conscientiousness with massive amounts of footnotes and unnecessary usage of words that were meant to impress but which really just sent me in search of a dictionary. I never leave book reviews. But with 150 pages still left to go I feel compelled to say don't waste your time. Surely there is a more clear and concise version of Laura's biography available somewhere.
