In 1931, a fall severely injured Carmichael, and she remained bedridden for much of her final two decades. However, it did not stop her from continuing her inspirational writing, for she published 16 additional books (including "His Thoughts Said . . . His Father Said" (1951), "If" (1953), "Edges of His Ways" (1955) and "God's Missionary" (1957)), as well as revised others she had previously published. Biographers differ on the number of her published works, which may have reached 35 or as many as six dozen, although only a few remain in print today.
