How many boeken are there and what are the names???

I dont think they are, L.J.Smith intended to leave the boeken at the Reunion but she got badgered door fans and carried on with The return: Nightfall, The Return: Shadows (To be released 16 March apparently) and then after that there is Midnight (Scheduled to be released on 1 July -not confirmed-)
Hope that helped a little x

the awakening
the struggle
the fury
the dark reunion

the return triology:
nightfall
shadow souls (march 16 2010)
midnight (december8 2010)

i'm not quite sure about the dates... :)

no the return vampire diaries boeken will be called the return trilogy which will be part of the vampire diaries boeken it will be part of the other vampire diaries boeken except the only difference is it the 3 boeken in the return series is that the titel of each book will say the return nightfall return shadow kisses and return midnight it will be be writtin door the same auteur lj smith she decided to do new series because she thought since she took 17 years away from writting and that 17 years was to long to keep writting the same vampire diaries series so she thought it would be good to write a return series for vampire diaries. here's the vampire diaries web site so u can find out meer about the vampire diaries series and also the return vampire diaries link hope this helps u out with what u were asking.
