Olivia and Ivy, the twins, have been invited to a royal vampire wedding. This trip is incredible with a beautiful castle, famous vampires, and the wedding of the century. Transylvania isn't all black-tie bats and wedding bells, as Ivy is supposed to be scoping out the famed vampire school Wallacia Academy. It would be an amazing opportunity to go to this boarding school, but does she want to go to a school that her human sister cannot.
