Fireflies

When global warming finally hit it's peak and all the ice melted, nearly 70% of dry land disappeared under water. The level of crime grew to the point where police couldn't do anything about it and the system crumbled. Now what's left from dry lands and big cities is ruled by gangs who fight for new territories. Fireflies is one of the biggest gangs, it's leader known for cruelness and cunning ways to gain more power.

Gabriella is a runaway, trying to escape from the previous gang she was part of and find a peaceful place to live in. Things don't go quite as Gabriella was hoping when her pursuers catch up and she is forced to trespass on Fireflies territory. Not before long Gabriella is captured and brought to the leader of Fireflies, Enzo.

Strangely enough Enzo doesn't kill Gabriella, but instead involves her into a game. If Gabriella can escape in one month then she is free to leave without being followed. However if Gabriella fails to do so, she has to stay with Enzo for forever.
