They were two voices on the telephone late at night. Burke was a construction engineer in Tampa for an extended assignment, not knowing how lonely he was. Nor did he know that Marti, the voice of Suncoast Answering Service, was disabled, ready to spread her wings in a world that would see her cane and limp before it appreciated her talents. Together they will learn that the hardest step is to learn to trust again.
