Seventeen-year-old Amber's mission in life is to ruin Bradley Jameson. Bradley deserves it––his false accusations of embezzlement drove Amber's father to suicide. And he needs to pay.
Amber creates a new identity to seduce Henry, Bradley's son
her ticket to an invite into Bradley's home. In her first of many attempts to destroy Bradley This could be strengthened (it clearly implies she fails, maybe make it more of a question... "Her first plan to destroy Bradley involves..." or something such, Amber plants drugs in his library and sends a tip to the cops, hoping to wreak havoc. Instead, the cops that show up turn out it might help to condense this "show up turn out" bit to be crooked––they're on Bradley's payroll and leave without questioning him. Amber's after a man who's proving to be untouchable.
Things get complicated when Amber encounters an old admirer. It’s Bradley’s nephew, Johnny
a charming playboy. Can you frame this as more of a "Not only that, but suddenly Amber is on a timer: Bradley's nephew Johnny comes to visit. As an old admirer, he knows who Amber is, and she needs to get rid of the charming playboy before..." You know, give a sense of urgency rather than complications? Amber needs to get rid of Johnny before he exposes her true identity and gets in the way of her scheme. But as much as Amber hates to admit it, the more time she spends with Johnny, the more she wants to kiss him, not make him disappear. This is better, but I'm still not totally sure how Johnny fits into all this... can you be more specific as to why he shows up, when they're spending time together, etc?
Bradley and his son are getting suspicious and with each scheme Bradley wriggles out of, she gets closer to being exposed--- time to complete her plan is running out. Now Amber must choose between pursuing revenge against a powerful man, who could frame her like her father with a snap of his fingers, or bail on her plans and live the rest of her life knowing she's let her father down. This last paragraph could be strengthened, I think just with rephrasing (see what other people think)
Much better! Overall, the whole Johnny paragraph is tripping me up. I simply don't see how he fits in well, beyond being a convenient plot device and love interest (I'm sure he makes sense, it's simply not being conveyed to me). Hopefully this all helps!
