I loved the twists in this. I figured out one quite early, but there were still several left that I didn't see coming.

note: one of the characters is disabled (she read as autistic to me, but I'm allistic so I might be wrong) and it's a double edged sword, because 1) there is ableism against her by her mother and outsiders, 2) by her sister, there is a kind of idealisation as this mystical, supernatural person. It made me a feel a little strange, but it's not really my place to judge if it's really bad rep (or it's never made clear what she is supposed to be, so).
