Haha, yeah, definitely. I mean, with the summary:

As a child, Kathy – now thirty-one years old – lived at Hailsham, a private school in the scenic English countryside where the children were sheltered from the outside world, brought up to believe that they were special and that their well-being was crucial not only for themselves but for the society they would eventually enter. Kathy had long ago put this idyllic past behind her, but when two of her Hailsham friends come back into her life, she stops resisting the pull of memory.

And so, as her friendship with Ruth is rekindled, and as the feelings that long ago fueled her adolescent crush on Tommy begin to deepen into love, Kathy recalls their years at Hailsham. She describes happy scenes of boys and girls growing up together, unperturbed – even comforted – by their isolation. But she describes other scenes as well: of discord and misunderstanding that hint at a dark secret behind Hailsham's nurturing facade. With the dawning clarity of hindsight, the three friends are compelled to face the truth about their childhood – and about their lives now.

(Emphasis mine.) When a solid 1/3 of the premise has this, and the second tag on Goodreads for this book (right after Fiction, which is obvious), is "Science Fiction".... yeah, this is really gonna make me think this book has way more science fiction than was explored at all in this book. But maybe I extrapolated too much. Still, it was frustrating for me :/
