Princess Adelaide of Acuniel forsook her dreams of a love match the day she agreed to a marriage treaty with the Crown Prince of Trilaria. While nothing like her childhood expectations, her life with Prince Miles is simple, comfortable. But then a plague ravages Trilaria, leaving her a widow and the kingdom without a ruler, and her new life is thrown into chaos. Her mother-in-law begs her to return to her father's house, but Adelaide refuses, pledging to stand by the newly widowed queen and the kingdom she has come to love. No matter what the future may hold.

Two potential heirs are found in the twin nephews of the late king, but only one can ascend the throne. Upon the discovery of critical information, Adelaide's mother-in-law contrives a daring plan to have the right man chosen. Acting on this plan could cost Adelaide everything? Or it could open the door to a future beyond her wildest imaginings.

The Love of a Princess is a loose retelling of the Biblical Book of Ruth, and is a sequel to Ashton's debut novel, The Peasant Queen: an Esther Retelling. While some characters connect, either book can be read as a stand-alone novel.
