Meh, I would say a negative on the Twilight books myself.
They are a pretty easy read. They are along the lines of Harry Potter, but clearly not as well written. HP is much more deep to Twilight's fluff.
I have only read the first 2 in the Twilight series, and I am not sure if I am going to continue. Not to sound like a brat, but if you are like me, and the story turns out differently than you hope it to, it just puts you in a bad mood.
Seriously, after New Moon, I was in a sour mood for like a week. I may finish the series just to be done with it, but since I have an idea how it will end up, and I do not like it, I am just not sure it is worth it.
