The Lost Girl of Astor Street by Stephanie Morrill, 345 pages (advanced reading copy)
It's 1924 in Chicago, and Piper Sail is a plucky teenager, soundly rejecting the ways of a proper lady that are being taught at her private girls' school. That tendency for trouble comes to a head when Piper's best friend Lydia goes missing from their tony neighborhood and Piper suddenly finds herself investigating Lydia's disappearance alongside an easy-on-the-eyes detective. Throw in some mafia ties, a speakeasy, and a couple of fast-talking newspaper reporters and you've got yourself a fine 1920s Chicago tale. It's fun, it's quick, and it's got a great heroine (think Veronica Mars with a little less noir). This one comes out in February 2017, and it's worth a look if you enjoyed Libba Bray's Diviners series.
