The Vampire Academy 10th Anniversary Edition is just the first book in the series but it contais some short stories that we never got to see before. 
 * The Turn and the Flame. 
 What happened that tragic day that Christian's parents turned Strigoi. 
 * From the Journal of Vasilisa Dragomir. 
 In which we see what Lissa went through after her family's death and how she tried to cope with it. 
 * The meeting. 
 This is the first time Dimitri and Rose meet but this time we are reading it from Dimitri's POV. 
 and 
 * Hello, My Name Is Rose Hathaway 
 is a cute little Rose/Dimitri story that we needed in our lives. 
 Since I wasn't a huge fan of the first book to begin with, I just skiped to the stories of Rose and the others. If there is any more contex in the main story... I have no clue but I doubt it. 
 It's still worth buying since it is a special edition.
