Forever - Mono x Six - Little Nightmares
23 parts Complete Cover by Gabawook
The sequel to the first book in the series, "Together." I HIGHLY recommend you read that book first so you can be all caught up on the events that have been unveiled so far.
Six & Mono flee from the Pale City after encountering its most dangerous inhabitants and destroying the Signal Tower, they find themselves stranded on a beach. With no way of transportation, they take any rescue that they can and find themselves yet again running and fighting for their lives against a new set of monsters in a brand new environment.
And let's just say, they might encounter another companion along the way.
This is the second fanfiction I've EVER made, so if the quality isn't the best, I would appreciate it if you would write any criticisms or constructive comments for me to read. I will try my best to improve!
