Bab: A Sub-Deb by Mary Roberts Rinehart

4.0

Bab is a great deal of fun, completely clueless, and a terrible speller. She chafes at being a "sub-debutante", just 20 months younger than her elder sister, who of course must be married off first. Pure teenage impulse and enough money to get into all sorts of scrapes. With the dawning of the US involvement in WWI, the plot takes a bit of a turn, but Bab's personality is such that she goes full-tilt at drilling and uniforms and hanging out the flag with guileless selfishness.
