Rory Power? Really? Eeh! Maybe, but I have my doubts. If Kirkus thinks this is a "staggering gut punch" that's enough to put me off it for life. The plot has it that "a mysterious illness sweeps through the Raxter School for Girls, Hetty breaks quarantine to find her missing friend - and makes a shocking discovery that upends their entire world." Yep. 'Shocking' is another bellwether word in a book description - warning you to avoid it like the plague. Dual narrators is just one more turn-off.
