Just twenty days from the wedding, Ellie’s mountain getaway turns into the moment everything falls apart. A conversation between Nate and his childhood friend Serena, along with a deleted message she wasn’t meant to see, makes the truth impossible to ignore. She leaves the trip behind, walks through the storm down the mountain, severs all ties, clears out the wedding memories, and shuts Nate out for good. As he waits alone in the church on what should have been their day, Ellie is already on a south-bound train, choosing a brand-new beginning.
