I agree with papersky about expectations about the YA content.
I'd expect it not necessarily to be lighthearted but to contain some humour, especially at the start. I'd be more likely to pick it up if the cover suggested that the idea of 'saving the kingdom' is looked at from different angles (as opposed to 'Kingdom needs saving, small band of plucky people save it, everyone lives happily ever after'), and less likely if the cover suggested something by Robert Asprin or Tom Holt.
I think that the title (in the absence of other information) suggests that a secondary-world fantasy with a roughly Medieval Mid/North European monarchy is the most likely of several possible options, but I wouldn't find it particularly odd if that wasn't the option chosen.
