Rereading the YA fantasy novel that first made me look up the term "chthonic" ("chthonic railway", specifically). Golden compass has the most compelling steampunk setting that I'd yet encountered when I first read it back in 2007, & it still holds up well reading the 2nd time around. The story also has a lot of heart. I feel like I should have read the Dark Materials series earlier. Looking forward to reading the Subtle Knife, as soon as I can find it in the pile of books it's buried under.
