Pretty Little Liars #2: Flawless, Sara Shepard

The Backstory: In the second book of the scandalous Pretty Little Liars series, Spencer, Aria, Emily, and Hanna are still getting creepy messages from someone named "A." At first, they thought it was their former BFF, Allison (who'd been missing for two years), but she recently turned up dead. Who knows the girls' secrets and is threatening to spill them all? The former friends have to band together and find out, before A's threats turn into actions and ruin their perfect little lives.

Perfect For: Sophisticated sistas who love a little mystery.
