My first thought: Sara Shepard wrote an adult book? Hmm..interesting. 
 My second thought: Upper East Side?! Yes, please. 
 Told with elements reflecting Shepard's Pretty Little Liars and binge marathons of Gossip Girl, The Heiresses may not have been a literary masterpiece but it was definitely the perfect vacation read. 
 As the title suggests, the characters are a part of the elite but have been rocked by family tragedies dubbed as the Saybrook Curse. So, in a nutshell, rich people start dying, affairs AFFAIRS EVERYWHERE, more sexy times, designer name dropping, more mystery and, finally, the big reveal: WHO'S THE KILLER? 
 If you liked Pretty Little Liars, you'll like this one. Sara Shepard really knows how to write a scandal.
