Teenage Mutant Ninja Turtle-Origin-new history

All 3 parts, only just finished & wanted to put it on-line to gain some feedback, so please R/R. I'm a fan writing for fun and wanted to put my take a more grounded tmnt world. Forget Splinter & Shredder and welcome Shiro & Shre Ard. There could just be a few errors/mistake, but it wont take away from the story i hope you enjoy check out my other stories!
