The story of River and Sierra begins with a seismic shift in boundaries: Sierra Grey, an intensely private and highly respected university Architecture Professor, unexpectedly finds her life upended by River Rutherford, intersex, charismatic, secretive, and fiercely intelligent transfer student in her program. Their initial connection is charged with intellectual sparring and undeniable attraction, blurring the lines of professional decorum. River, however, harbors a secret far greater than her student status: she is the elusive Rutherford heir, navigating immense corporate pressure and familial expectation while struggling to pursue her own architectural passion. The couple retreats to Sierra's remote childhood home to confront the lie, where their connection deepens through vulnerable confessions and intense, clarifying passion.
