Youth and Whisky
I absolutely LOVE The Vampire Diaries book series.
It's one of the best ones I've read (and reread)
Also I recommend the Hush, Hush saga, fantastic!
If you don't want a series, I suggest the Immortal Rules, or the space between, both are absolutely amazing
The Vampire Diaries were okay. It was a little too much geared towards teenagers for me, well, so it seemed.
And who are the authors of the Hush, Hush saga and the other two books you recommended?
