The Girl at Midnight is going to be massively popular. At least, it should be. It has all the things a big hit needs: inventive world building, fun characters, non-stop action, a sense of humor, end-of-the-world stakes, and more than a little dash of magic.
Seventeen year old Echo has grown up among the Avicen, a society of feathered people who live alongside our own in secret parts of New York. Magic is real, Echo can use it, and she spends her days jumping around the globe, stealing the valuable and the interesting for herself and her adoptive family. But when Echo steals something that seems to hint toward the location of the Firebird -- a mythical creature that could end the wars between the Avicen and their enemies, the dragon-like Drakharin -- she's tasked with finding it before the Drakharin do and ending the war in her adopted people's favor. But many among the Avicen do not want her help, and the Drakharin will not let her take it without a fight.
It's a difficult book to describe, but an incredibly fun book to read. Frequent readers of YA fantasy will find that the second world theme and the whirlwind tour of international cities is reminiscent of Daughter of Smoke and Bone, while readers of Cassandra Clare's series will find a lot of the banter-filled dialogue and characterization familiar. But The Girl at Midnight also has a strong voice of its own, with plenty of world building and plot-twistiness to ensure it feels unique. It's a diverse read, with lots of female friendship and mentorship, an unusual protagonist, and a really fun romance, and it practically demands you devour it at a breakneck pace before begging for its sequel.
If you're a fan of YA, definitely pick this one up, especially if you have a vacation or a long plane ride in your near future. It'll suck you in and make the time fly by.
