Does this sound like a good book series idea? Best Answer 10 Points!!!?

Okay so long story short, 3 girls and 2 guys get trapped in alternet world were they have to go through 16 "stages" and most survive 10 days in each stage, if they survive they live and become the new rulers of Syria. They were chosen from the evil king of Syria, who has made a deal wtih all of Syria, if they win the can take his place, if they loose he will rule forever. There are romantic issues between three of the characters, and two characters die. its kinda hard for me to explain, but the 5 main characters just wanna go home, so they do everything they can....... sorry i am kinda rushing, i dont really know how to put it into words but i hope u get the jist of it:) THANKS!!!
