i definnily don't think they kiss in awakening یا the struggle because ive read those کتابیں and also they don't kissin fury یا dark reunion so ill have to wait til i read night fall and also shadow souls. to see what happens between damon and elana.
i think that they had kissed in the fury( 3rd book) when Elena wakes as vampire and think that she's in love with Damon, they'd also kissed in the Nightfall (5th book) when she's healing him from malach, and in Shadow Souls they are kissing almost all the time, hope I helped :)
I've read the descriptions of the books, آپ know the bit on the back of them that only gives a little bit away? No idea what it's called. Well, Damon and Elena NEVER actually get together, not according to the texts. But they kiss in the The Vampire Diaries; The Return: Nightfall plus. I don't think they do anything in the last one, need to wait and see when it comes out! Can't wait!!
