In an Edinburgh shaped by Alpha, Beta, and Omega dynamics, male Omega Elliott Hale carries the scent of mint after rain but feels increasingly invisible inside a 99.7-percent match. When jasmine pheromones on his Alpha husband expose an affair, Elliott seeks out Julian Ashcroft—the other betrayed spouse. Once a brilliant physician, Julian was left permanently unable to smell or produce pheromones after an attack. Their search for the truth becomes an unexpected refuge. One man reads the world through scent; the other lives beyond it. Together, they must decide whether love is written by biology or chosen with clear eyes.
