Flawless

Spencer, Aria, Emily, and Hanna are four attractive little liars who have been very naughty girls in the upscale town of Rosewood, Pennsylvania, where the prettiest smiles conceal the deepest secrets....

Spencer made off with her sister's partner. Aria's English instructor has crushed her heart. Emily views Maya, her new buddy, as much more than just a friend. And Hanna is physically becoming ill from her fixation with having a perfect appearance. However, the most terrible secret of all is something so outrageous that it has the potential to ruin their idyllic little existence.

And there's a threat from someone going by "A" to do precisely that.

They first believed that A was their buddy Alison, who disappeared three years before, but Alison later ended up dead. Is Melissa, Spencer's fiercely competitive sister, A? Or Maya, who wants exclusive access to Emily? What about Toby, the mysterious guy who left town right after Alison went missing?

There's no doubt about it: A has the dirt to bury them all alive. The girls are getting closer to losing everything with each rumpled note, nefarious instant message, and resentful text message A sends.
