Almost an Angel

In the last ten years, Carolly Hanson has died six times. First in a car crash, then of TB. Beaten, stoned, and shot in the back. The last time, she suffocated from pneumonia.
Now she's awake, again, and in the arms of James Oscar Henry Northram, Earl of Traynern.
Carolly Hanson must be in training to be an angel. Why else would she keep dying and reappearing in different places and times? Clearly she is to help people, help them find true love, if she is to win her wings.
And the handsome Earl, clearly a stiff-backed, dark-brooding man of means, will be her next victim-er, beneficiary.
James Oscar Henry Northram is fascinated by Carolly's odd sense of humor, and compelled by her strange forthright manner and complete lack of interest in trapping him into marriage.
He also thinks poor Carolly is a Bedlam escapee and isn't the least bit interested in the women she keeps pushing in his direction.
Why must Carolly be forced to suffer death only to live again? Could the answer be as close as his embrace?
