Fun closer to the best musical theater demon trilogy around.
After the bloodbath of the series’ second volume, Knudsen lightens up on the gore (though there are a few violent demonic encounters) and allows Cyn’s acerbic wit and WTF attitude to shine through.

As ever, there’s a lot of Buffy-worthy silliness and snark grounded by a strong foundation of well-developed characters and relationships. Cyn and Ryan’s sweet romance and one last pitch-perfect musical number round out the satisfying conclusion to this horror-comedy saga— although Cyn’s foreboding dreams/visions at book’s end suggest there may be an encore.

Curse of the Evil Librarian is a fast, funny, and irreverent almost-end to the series.
