Ruthless (Pretty Little Liars, #10)

For years scandal has rocked Rosewood, Pennsylvania - and high school seniors Aria, Emily, Hanna, and Spencer have always been at the center of the drama. They've lost friends, been targeted by a ruthless stalker named A, and narrowly escaped death. And it's not over yet.<br /><br />Aria's love life is on the fritz. Emily's exploring her wild side. Hanna's kissing the enemy. And someone from Spencer's past - someone she never thought she'd see again - is back to haunt her.<br /><br />But none of that compares to what happened last spring break. It's their darkest secret yet, and guess who found out? Now A is determined to make them pay for their crime, and the only thing scarier than A is the fear that maybe, just maybe, they deserve what's coming to them.
