I've kept some of the character types you have to choose from the original tag, but also added/altered a few just for my own enjoyment. And if any other bloggers out there want to give it a try then please do!
So, without further ado, let us begin!
1) One character can can/likes to cook
Perhaps a bit of a weird choice, but I would invite Hannibal Lecter. As long as you're not rude he's a perfect gent
2) One character who owns a house/estate/apartment/palace where you would like to host your dinner
I'd go with Chandresh from The Night Circus. Just imagine eating your dinner in that circus, and you'd have some great entertainment!
3) One character who would bring the best presents
Maybe a bit of an odd choice, but Sherlock Holmes. He's done so many bizarre things and been to so many different places that I feel as though he'd just have an accumulation of weird stuff to hand out to people at Christmas.
4) One hero
Harry from the Harry Potter series. That guy must have had so many awful Christmases as a child that I'd love to invite him over for a great party.
5) One heroine
Georgia Mason from the Newsflesh trilogy. I love her, and I'd love to have a conversation with her.
6) One villain
Jude from the Noughts & Crosses series. I suppose it's debatable as to whether or not this guy is really a villain, but he certainly ain't pleasant. Having said that he always fascinated me, so I'd be interested in listening to what he had to say for himself.
7) One romantic couple
Cinder and Kai from The Lunar Chronicles. I love these two a lot.
8) One non-romantic couple
Katniss and Prim from The Hunger Games. These girls need some good food to eat.
9) One under-appreciated character
Rubeus Hagrid. Such an awesome guy who gets barely any credit, why Harry and Ginny named their son after Dumbledore and Snape and not this guy I'll never understand.
10) One character of your own choosing
I will always love Sirius Black, so he'd be given that extra seat at my dinner table.
If you'd like to have a go at this then go for it! I'd love to see what your answers would be.
