If this book met that book

[Kynkynsmc, The peace keeper]

Ok it's pretty self explanatory, so the first person says " if (book series) met (book series) what would happen" then the other person would put what would happen and continue

[Juliet, Professional fangirl]

Harry Potter + The Mortal Instruments = war between the Shadowhunters and the wizards. :o

[~Reading Rambler~, Reading Rambler]

Vampire Academy + Percy Jackson = The Greek Gods will have to fight the evil strigoi!

[Jess]

Thg + divergent = war over whether there should be 5 factions or 12 districts!

[Juliet, Professional fangirl]

^^^ Also I think Jeanine and Snow would get along well. :P

[Jess]

Oh my gosh, if Jeanine and Snow were in the same book everyone would've died by the first chapter!

[Juliet, Professional fangirl]

xD Exactly! World war III right there!

[Maya]

Vampire Academy+ Mortal Instruments= a way to cure the Endarkend
