The Left-Handed Booksellers of London (Left-Handed Booksellers of London, #1)
by Garth Nix
Not particularly well written (so much awkward exposition! is it really realistic for an 18 year old to be an expert in art history and antiques, even if she does have a (stated, not shown) desire to be an artist?) but it moves fast and ultimately it was a lot of fun. Many of Nix's favorite tropes are here (girl questing for her distant/inaccessible father, ancient evil and zombies, the overlap of the mundane world and magic, the competent-but-out-of-their-depth (para)military officer trying to be helpful and only occasionally succeeding), but recombined and remixed.
I liked where Nix left the relationship between Susan and her father emotionally. Also, the main character is quite butch and the love interest is genderqueer/transfeminine/questioning, which is always a draw for me....!
Looking forward to reading the next one(s), also I hope someone's done fan art.
