Will the key unlock more than a vault filled with treasure?

Brooke Sumner has been carefully avoiding Storm Whitlock ever since he betrayed her trust. When he joins Caspar's mysterious treasure-hunting group, she steps away to focus on her antique shop and keep herself busy.

When Caspar invites her back for one final assignment, Brooke is torn. Returning to Halstead Manor to help the team find the second half of a key is intriguing. It also means she'd be working with Storm. But she doesn't trust his motives, so she reluctantly rejoins to keep him in check.

As they dive into their expedition, Brooke finds her heart softening toward those she'd once held at arm's length. And is it possible she misunderstood Storm's betrayal of their friendship?
