The Amber Spyglass by Philip Pullman.
Everything is fine, nothing is answered
This one just didn't do it for me, despite not being meaningfully different to the preceding two. Part of it was definitely a bit of ick from two characters I very much saw as kids (Lyra's ~12 in this book!) suddenly being very interested in romance. I mean it makes a lot of sense, most kids are at that age even without the extensive trauma-bonding, but much like their other authentically child-like reactions and decisions it's just not fun to read for me.
Something else...
