Do you think we could all just read The Night World series? I mean, it has witches (the guys could be considered wizards), vampires (for those Twilighters), werewolves (for the other side of the Twilighters), AND shapeshifters!
Lots of romance too:
Poppy & James (vampires)
Mary-Lynette & Ash (vampires/humans)
Thea & Eric (witches/humans)
Gillian & David (witches/humans)
Rashel & Quinn (vampire hunters/vampires)
Hannah & Thierry (reincarnated humans/vampires)
Jez & Morgead (vampire halfbreed/vampire)
Maggie & David (human/vampire/insane witch lady)
Keller & Galen (shapeshifting panther/future shapeshifter)
And there's werewolves and witches mixed in with all of them. Including a werewolf halfbreed, Lupe. The insane witch lady is Sylvia. You people really should read it.
