Flynn's cousin Suzy, once married to Marshall Beckett, reveals details of her awful marriage to a tyrant. She begs Flynn to see if the son she left behind is okay and locate her hidden diary, a "matter of life or death." Flynn is at a crossroads in her life where she can renew her contract as a world-traveling concert violinist or search for what she really longs for--a home, with a special person to love. She arrives at Marshall's horse ranch, Rainbow's End, under the pretense of answering his ad for a nanny. But Suzy had failed to tell Flynn that in the same ad he advertised for a wife. This rugged, coppery-haired rancher is burned out of love and wants a woman to bear him children, without investing any emotional commitments. When they decide a marriage of convenience is the only way to save Rainbow's End, sparks fly between them.
