Sophia has spent her life ping-ponging between different countries and schools, so, in theory, saying goodbye should be easy. But now she's leaving Tokyo - the place that finally felt like home. The only way she can get through this is to make her final week perfect.

Then Jamie Foster-Collins shows up, just in time to ruin everything. Jamie and Sophia used to be friends . . . and his return stirs up feelings she thought she'd forgotten.

Suddenly, hours and minutes become meaningless. Only time spent together, exploring the hidden streets of the city they love, is real.
