Two Once There is the sequel to Two Once Removed, where Callie Larson and Jason Cartwright come together again as life continues to move forward and unravel at the same time. Through their journey, more truths uncover, as their extended families make their realities more painfully clear.

In the months that follow their impromptu weekend of rediscovery and Callie's cryptic Thanksgiving Day text saying to "wait for her", Jason invests in a mountain retreat after staying there over Christmas and New Years. The purchase is kept secret as he suspiciously travels back and forth to Asheville, North Carolina near where the retreat is located.

With her kids on vacation in Nantucket with her soon-to-be ex-husband, Callie makes her return to the beach searching for Jason. Her trip is intended to be a surprise after holding her promise of complete silence while she focused on resolving her marriage issues to a final decree. When she arrives at the beach, Callie only finds his daughters who immediately recognize her as the mystery woman in the photograph on Jason's kitchen counter.

The events that follow draw in family and friends to both combine and collide into a new reality for both Callie and Jason. Their agreed absolute silence, followed by missteps, misunderstandings, and a single family tragedy, challenge their destiny to be together to not be as absolute as first thought.

Two Once There is an intense, emotional story about taking the step from mid-life, loveless marriage fantasy to reality. Parents, children, friends, and geography add to the blend as both Jason and Callie learn more about what a life together would be, and how it would affect them and their lives with their families.
