 In 1977, while riding his motorcycle, McKiernan was hit by a car that had crossed the center-line, and he was confined to a bed, first in traction and then in a hip spica cast, for many months.During his recuperation, he began a sequel to J. R. R. Tolkien's "The Lord of the Rings".The publisher Doubleday showed an interest in his work and tried to obtain authorization from Tolkien's estate but was denied.
