umgowa,
I think people here "hate" prologues for any number of reasons, but it you look through the first ten pages of threads in "novels" and "Basic Writing Questions" you will probably find at least three prologue threads. And you can see how folks here like them, and then consider how many agents you possibly want to pre-weed with a clunky prologue in the query
Agents are busy, and agents are looking to say no, not because they want to crush you or fail themselves, they all want the next best thing, but they have mountains of queries. they're working triage. Things look so exceptional they will continue, or anything less they will toss aside instead of hunting through the whole thing to the bitter end just in case there is a nugget somewhere in there. If a number of them view prologues skeptically, you don't want to start out with one foot in a hole and then have to work it out again--selling is plenty hard as it is. A brilliant story would brobably let you pitch with the salutation "Yo, Bitch," too, but I'd advise against it.
The bigger issue in your case is the fact you put a good chunk of prologue in your query; you devoted like 1/3 of the query to setting up what I assume is like ten pages of your book, or 1/40th. Does that seem like a good return on effort, especially since the prologue is usually arguably disposeable?
as for questions, like ciya said, it is easy to say no...or worse, to ridicule.
"Have you ever wondered what it would be like to be a battle-scarred alien space captain?"
maybe, maybe not. Even if I go "huh, yeah, just the other day..." it still isn't as grabbing as actually starting the story:
"Rex Deacon has damn few rules for his ship, few enough he can tick them off on the wreckage of his right hand without needing the six fingers on his left."
people THINK the questions open an agent up, but do you have kids? Ever really busy, and then they come up and say
"Umm, Dad, I, uh, um, I was talking to my brother, and um, if you say no, that's ok, but, um, we were wondering, if it would be ok, and if it isn't then that IS ok, but..."
until you're biting back a "Oh my god, just fucking get on with it!"
Ever have that? agents are busy too, and if you ask a question, you're the one "not fucking getting on with it".. a random question may mark you as an amateur, it may lead them to a shrug and moving on, because their answer wasn't the one you were looking for, it may lead them to move on to someone who can actualy get their show on the road because they're busy and apparently you'd rather play guessing games than get your story moving, etc..... Conversely, what do you think the question offers, and more importantly, what does it offer that you can't get by actually grabbing them right off the bat, and LEADING them, instead of asking a question and hoping they choose to follow?
