Meet me at infinity Book

This is a good book for those who are not familiar with the story of James Tiptree Jr., as the majority of pages are letters to the person who compiled these previously uncollected works. A good book to get to know Alice Bradley Sheldon, and track the writer's career. Especially interesting - naturally - is the difficulty she had getting published and collected after the world found out she was a woman. There is an unfortunate hint in this book that part of that issue was that maybe her writing style changed when she wrote as a woman. I need more evidence of that before I accept that implied premise.
