Dijkstra's another one of those powerhouses you either love or hate. I've heard some stories about her, and know a few of her clients. I don't think I could work with her.
I also couldn't read Blind Submission. I tried, but the characters felt like cardboard and there was a lot of telling, not showing. Maybe the whole thing pulled together later (and it could have, because it's gotten good reviews), but it didn't work for me and I gave up after 30 pages.
If you want to read a funny chick lit type book about publishing, try Marian Keye's The Other Side of the Story.
