Born in New Haven, CT, in April 1935, Ida Curtis grew up in a small town near Hartford, CT. After marriage, she and her husband raised a family of two children, moving around the United States as his academic career dictated, living for the longest period in Vancouver, British Columbia. After retirement, they moved to Seattle to be near their son and daughter. Based on a handbook written by a ninth-century widow of a wealthy landowner to educate her sons, Song of Isabel captures what life was like for a young noblewoman of that period.

Just before taking her vows, Sister Gilda, along with Lord Justin, King Louis's counselor, is given a task: investigate grounds for the annulment of a marriage between Count Cedric and Lady Mariel. Together, they discover that Mariel believes she actually married Cedric's younger half-brother Phillip—Cedric's surrogate—at the marriage ceremony, and that Cedric plans to marry Lady Emma as soon as the annulment is granted. Emma and Phillip, meanwhile, have declared their love for each other.

Gilda and Justin must find a fair and just solution that will satisfy the principals, the archbishop, and the king—and at the same time deal with the distracting passion developing between the two of them. As they work together to unravel the mysterious circumstances of the count's marriage, their attraction grows—threatening Gilda's freedom and Justin's reputation.

Set in ninth-century France, The Nun's Betrothal is a suspenseful, romantic tale of court intrigue and forbidden love.

Lady Isabel is just twelve years old when Lord Chetwynd rescuesher from being raped by warriors in his company. When they meet eight years later, each has a good reason for entering an arranged marriage. Together, they embark on a perilous journey to the court of King Louis. On the way, danger from enemies on the journey brings them closer together; when they arrive at court, rivalry and intrigue nearly parts them. Ultimately, however, they survive these trials through their own native wit and charm—and gain new respect and love for one another. Rich with historical detail and drama, Song of Isabel is a compelling novel of love, sex, ambition, and intrigue.
