Daniel's romantic proposal may come with dire ramifications; Charlotte is forced to move back in with her mother; Jack's life is in jeopardy when a person he adores betrays him; Nolan makes Emily think cautiously about her actions.

With the end in sight, Emily fearlessly pushes forward, closing in on the final phases of her plan for revenge, while the Graysons continue their downward spiral into the rabbit hole of self-destruction. But a big, explosive event leaves much hanging in the balance, courses are altered and even more is left in question.

In the wake of last summer's events in the Hamptons and with the ante even higher, what will Emily's next move be? Will she be able to manage her heart and keep her emotions from getting in the way of her resolve to avenge her father?
