I remember reading back in primary school a series of short stories, one was about a brother and a sister who go through a traumatic alien abduction, leading to the brother want to return to the aliens, who only want his sister, so she is kidnapped at the end.
Another is an infestation of flesh eating insects who cannot be culled. I can't remember this one as well as the first. They were illustrated in black and white, does anyone have an idea what series I read? Thanks!
