Once they had it all.
Callie and Morgan Rutherford's courtship and marriage is a dream come true. They have everything two people could ever hope to attain: success in business, wonderful friends, and a loving family. In short, life is good. — Everything turns upside-down, however, when a freak accident sends Morgan to the hospital. After weeks of pain and surgery, he's a changed person. Gone is the tender, caring man of Callie's dreams. In his place is a remote stranger slowly withdrawing further and further into himself.
But is just the accident keeping them apart? Will Callie's love be enough to uncover the truth? Moreover, will this, Callie's most important challenge, be her last?
