The Birds of the Air by L. H. Arthur

Libby Barnett knows what she saw, but the adults in her small town don’t believe her. A strange man appeared in Libby’s backyard and transformed her little sister into a blue-eyed sparrow that flew away into the unknown. Now, 13-year-old Libby has no choice but to go in search of the lost bird that was her sister. Venturing out into the dangerous vagrant underworld of the Great Depression, she will find an even more secretive hidden world of dark magic she never could have imagined existed.
