This story is called Crossing over.
It is not only Gaara and Lee... it has a couple other pairings in it. The pairing that takes up the most chapters though is Gaalee.
Crossing overThere is the link to it. Chapter 4: The negotiation is where the GaaLee part starts, if you want to skip right to that. The other pairings include:
SasuNaru
ShikaKiba
KakaIru
And thar ye go. Please either review on here, or if you have a fanfic account be sure to review on there. ^___^
Let us summerise now:
This is set in America, back in the let's say... 60's when grasers dominated the streets. Lee is at first a normal athelete in school, with a boring life and un-fufilled dreams.... until the leaf gang attempts to mug him.
In this fanfic, the gangs have their powers, and they use those to mug people, fight, etc. More of a expaination in the fic.
The GaaLee plotline is a secret though! No hints for you! Besides, it would take forever to explain. -___-
This is a incomplete fic, but I will be done with it soon. Pretty much, the GaaLee main plot is finished.
