Why we recommend it

We don't broadly recommend Sadie for the 14–18 age band; see the notes above before choosing. It leans into mystery in a way that feels genuine, not formulaic. Courtney Summers's voice is what makes it stick: readable, respectful of kids, and easy to hand to the next child in the family.
