They Fade Away - Alex Armoredes - Bog

In this YA horror novella, Alex Armoredes pens the story of two classmates who are forced to work together in order to solve an otherworldly mystery.
Arwin Argyle expects another boring day at school. Instead he is met with a series of disappearances, but only he and his classmate, Emma Li, of whom he has rarely spoken to before, remember those who have gone missing. Everyone else seems adamant that they've never existed at all.
Suddenly they are forced to discover who or what is behind the mystery at the school, before everyone they know...and each other...vanish into thin air.
