We are the Ants, by Shaun David Hutchinson

Henry Denton has lived several years under periodic alien abduction. He has told the others about these frequent abductions, but it only earned him his new name, the “Space Boy.” But then everything changes when the aliens give him a working ultimatum.

Henry is tasked with stopping the end of the world. The world is to end in the next 144 days, and all he has to do for this not to happen is push a big red button. The problem is that Henry is unsure he wants to do this.

Their grandmother is living with Alzheimer’s. To add to all this, Henry’s boyfriend committed suicide, and he hasn’t healed from his grief. For him, it might just be better to wipe the slate clean.

But before everything else, Henry is a scientist, and he must handle this issue logically and thoroughly. That’s when he decides to analyze the pros and cons. He will have to examine his one-night stand bully, his best friend’s betrayal, and a brilliant boy who walks into the wrong class.

On that same day, she goes into the woods and finds a creature in one of them. It is inhuman, and that can only mean that it is an alien. Liv suddenly comes to terms with a painful realization- her dad didn’t lie about the aliens. But no one, including her, has ever believed him.
