In Bloodlines and golden lilly and so on... i know rose and lissa and dimitri aren't the main characters but do the libros still mention about them??

Yes they reapear in the later books

Dimitri and Rose aren't seen that much together but they are in the libros quite a lot por themselves with small mentions here and there of their exsisting romance. I really suggest lectura them. You're probably thinking the same thing as I was before readint them, that they aren't as good as Vampire Academy because they don't have Romitri in it. Honestly, they're great and I'm addicted to them now :D

I won't say much if tu haven't already read the books, but Dimitri and Rose appear in Bloodlines and The Indigo Spell. Only Dimitri himself appears in The Golden Lily, and Rose is mentioned in every book. I mean, she's Rose!

Dimitri is with all of the golden lily and part of bloodlines, but the libros where so bad that I suggest tu to not read them
