Personally, I wouldn’t say so. You can tell the difference just by width. It’s been a while since I’ve read either, but I recall reading Kingdom Keepers just because it was about Disney World, having no real connection to the storyline besides that.
Right now, I’m stuck on the Hunger Games trilogy. It’s for children/young adults, too, but very addicting. I was intrigued to read after all of the movie craze - and finished it in a day! Now I’m halfway through the second. I find this much more entertaining than the Twilight saga. The writing is better than Twilight, but still rather amateur. I’m finding myself annoyed at the second book because they keep re-explaining everything we learned in the first. I don’t like books that insult the readers’ intelligence, but I’m addicted to the storyline.
