UPDATE UPDATE: full synopsis (thanks to Lauren<3)
Eliza is in a full-blown panic. Her notebook has been stolen—the one that lists everything she wants but is afraid to go after. And the absolute worst person in the world has it: her ex-boyfriend, Cooper.
Like it’s not enough Cooper was lying to Eliza for their entire relationship, now he and his friends are blackmailing her. They’re giving her just one night to complete the most humiliating tasks on her list or they’ll post her secrets online—including the ones that aren’t just about her.
Eliza’s sure of only one thing: she isn’t going down without a fight. Cooper may have what’s left of her dignity, but she’s not the only one with something to hide....
Let's read this one on the night of July 20th 2010 and see if it changes anything :-)
