My favourite would be Eclipse, first because all characters have a better chance to shine in the story, besides only Jacob, Bella and Edward. There's more action, more suspense and more explanation to the whole story. Besides it's my first book!
Eclipse, because it made me laugh & cry so many times I lost track. The writing is so great. I love it when Edward & Jacob have there confrontation in Bella's front yard.
I’m not going to kill you now, because it would upset Bella.
But if you ever bring her back damaged again — and I don’t care whose fault it is; I don’t care if she merely trips, or if a meteor falls out of the sky and hits her in the head — if you return her to me in less than the perfect condition that I left her in, you will be running with three legs. Do you understand that, mongrel? (Edward)
I loved Breaking Dawn, I can really identify with Bella in some aspects in thisnovel, then probably Twilight, the excitement of new found love but yet still akward and nervous at the same time. I wish I could read them all for the 1st time again!!
