oh, and I think that the meaning is simply "it looks like it's about princesses and therefore it must be boring" --"and junk" just means "etc." or "and other boring things." Although "junk" does have a slang meaning of "drugs," that's not implied here except in my obscure reference to Telemakos taking opium! (or should I say, being given opium)

don't know if you've read the whole series--that happens later! of course, come to think of it, there is a boatload of drug use in The Winter Prince as well
