Characters

Twelve teens woke up to find themselves locked in a huge house together, and all they knew was that they had to finish some weird missions to achieve freedom and be able to go back to their homes. How will each of them deal with working with eleven other strangers?
(I know that there is a lot of these 'Zodiac House' books but this one is kinda different. Plus English isn't my first language so the grammar in the story is kinda bad)
