Outer Banks meets Pretty Little Liars in this explosive finale to Nora Blake's Grove Hills series.

What's the price of loyalty when the truth could destroy you?

Jorja thought she understood the dangers of her family's dark legacy, but the secrets buried in Grove Hills are deadlier than she ever imagined. Her grandfather's empire is closing in, and her every move is shadowed by betrayal, power, and manipulation. A mysterious key and a risky alliance with Bentley may hold the answers she needs, but trusting the wrong person could cost her everything.

As Toby and Rush work desperately to protect her, tensions rise, friendships are tested, and Jorja is forced to make impossible choices. With lives on the line and time running out, can she uncover the truth before it destroys everyone she loves?

This Little Promise delivers a heart-pounding conclusion where loyalty is tested, love is a dangerous game, and no secret stays buried forever.
