This Disaster Loves You by Richard Roper

From the author of Something to Live For, a poignant and funny story about a man whose wife disappeared seven years ago and his journey to find her or find out what happened, interwoven with the story of their relationship, revealing how sometimes the biggest secrets are the ones we keep from ourselves.
Twenty years of love. Seven years of absence. One journey to find out what happened.

Brian's wife, Lily, disappeared from his life without a trace six years, eleven months, one week, and two days ago, but Brian never lost hope. Since her disappearance their once beloved English pub—and Brian's livelihood—has been crumbling piece by piece. As the anniversary of her absence approaches, Brian desperately needs a sign. One doom-scroll on his business's reviews later, he finds it: an active TripAdvisor account for PinkMoonLily1972 that he knows in his heart is his Lily.
Interspliced with Brian's journey to find Lily is the story of their love—how it started, and the twists and turns that brought them to this moment. As Brian jumps from one destination to the next to find Lily, and the truth behind their story comes into focus, Brian comes back to life with the help of Tess, a sarcastic, kind, and surprising traveling companion. But in order to move forward he'll need to decide—stay in the past or take a chance on something unexpected.
