There’s another YA scifi series coming this May 2019. Called The Society, it has echoes of Under the Dome mixed in with Lord of the Flies, with a bunch of teenagers being stranded in a facsimile of their home city, sealed off from the rest of the World, and not quite knowing why.
Is it an experiment by aliens who want to see how long it takes for humanity to eat itself? A government conspiracy experiment?
Who knows? Perhaps a better question is, will anyone in the YA demographic actually care? We shall see.
