I've had a spate of queries recently that start with a question like "Have you ever wondered what it would be like to be a vampire?"
Which means I'm not engaged with your narrative, and that means PASS.
That's really not what you want, is it?
Don't start with a question that has a yes or no answer cause you really do NOT want to let the agent pass on you so quickly.
Instead, talk about how your character wondered what it would be like to be a vampire, and now she's getting the chance.
