Sara Shepard - Hibátlanok (2019)

Caution! Contains plot description.

In Rosewood, where the sweetest smiles hide the darkest secrets, there live four pretty little liars - Spencer, Aria, Emily and Hanna - who have done very ugly things...

Spencer reached down for her brother's friend; Aria was totally crushing on her English teacher; Emily really likes her new girlfriend Maya… but not just as a friend; And Hanna is literally sick of her obsession with looking perfect. But the most terrifying secret they all share is so scandalous that it could completely destroy their comfortable lives.

And someone who only calls himself A. threatens to do just that.

At first they thought it was A. Alison, their girlfriend who disappeared without a trace three years ago. But it was later revealed that Alison was dead. But then who could be A.? Melissa? Spencer's almost morbidly competitive brother? Or Maya, who wants Emily all to herself? And what about Toby, the mysterious guy who left town just after Alison disappeared?

One thing is certain: A. has enough evidence to destroy them. And with each crumpled letter, mean online message or vengeful text, the girls drift closer to losing everything.
