instead of saying "when does this book get to the representation i was promised" ask yourself "am i actually enjoying reading this book" and if you aren't, stop reading the book. unless you think it's going to get good on its own terms, i guess.
i also distrust anyone whose recommendation is just an 5 words and vague enthusiasm. especially if they are also an author. author recommendations are just for them to network with each other, you can't trust them to mean anything.
