Izzy Tierney is doing everything right.

She's got a job she's proud of and a passport full of stamps from her frequent work trips. Everyone keeps telling her she's living the dream—but it's starting to feel more like drifting. Constant motion is just another way to avoid standing still long enough to feel lonely. She tells herself she's content, but something's missing—something she's never quite let herself want.

Kiera Phillips is caught in a swirl of uncertainty. Newly divorced and living with her two daughters in her parents' house, she's trying to rebuild a life she no longer recognizes. A new city, no job, no real plan—and now even her closest friendships feel distant. She's doing her best to hold it all together, but the truth is, she feels completely lost.

Then, an invitation from the group chat: a weekend getaway to a beach house in San Diego. Izzy and Kiera agree, thinking it's just a short escape—how bad can it be? But what starts as a casual weekend quickly pulls them into deeper waters. Reconnected bonds stir up old emotions, buried truths, and unanswered questions. By the end, neither woman knows where she stands.

When real life rushes back like an unstoppable tide, they're left wondering if they can truly leave the past behind—or if their lives are about to change for good. What happens when the weekend ends, and you're left standing at the shore, knowing the tide has shifted?

Shift the Tide is a spin-off story of One Last Run, featuring two characters who kept stealing the show. It can be enjoyed as a standalone or the second in the series.
