Bronte O'Hara is raising her little nephew alone; she has a familiar, established life. But one day, trouble comes knocking on their house - the boy is diagnosed with leukemia, and only one person can be a bone marrow donor - the twin brother of the child's long-dead father. The last thing in the world Bronte wants to ask for help from such a cruel man as Lucas Blackstone, but she has no other choice. She does not yet know that this meeting will change the life of not only her nephew, but also her own.
