The Enemy series by Charlie Higson fanfic. Akill (Achilleus x Will) and takes place around the end of The End and beyond. All characters belong to Charlie Higson, and the cover is drawn by marcofelixed on Tumblr ( https://marcofelixed.tumblr.com/tagged/my-art ). Warning: most likely extremely bad. Cringey and cheesy as well. Also, note: I like not to use "language" in my writing (I sound like Captain America, lol), so no cursing here.
