A Team Fortress 2 and Percy Jackson Crossover Alternative Universe! This will be my first book about it!

A story about 9 mercs from the game called Team Fortress 2 got reincarnated to COTE turning them into a 16 years old teenagers.Will they survived in a school where it's filled with backstabber and manipulation? Or they will be expelled let's find out! This idea came from my shower thought and dont expect that this book is going to be good since im a new writer :/.And im doing it just for fun i guess :v NOTE:I do not own COTE or TF2 this is just some weird crossover and fanmade.And the book cover is also not mine

PS Best to read the rewrite at the bottom unless you want to die of cringe It's the year of 1967 and the end of the world has come, due to humanity the ozone layer had bursted and had started the extinction of our species. The mercenaries had survived due to being in the right place at the right time. What will our favorite mercs do this time? Perhaps escape to outer space? (PS this is my first book so excuse me for the mistakes in everything, also it's my Au and male OC insert though he will not be involved in the plot and if you don't like the ships, kindly stop reading OK. And I haven't watched RWBY at all) I do not own anything besides the story itself TF2 and RWBY belongs to their respective owners.
