Valancy Stirling is twenty-nine, unmarried and has never been in love. Living with her overbearing mother and a meddlesome aunt, she finds her only consolation in the ‘forbidden’ books of John Foster and her daydreams of the Blue Castle – a place where all her dreams come true and she can become who she truly wants to be.

Shortly after her birthday, Valancy receives news about her health that causes her to throw caution to the wind and make a fresh start with her life, finally finding the strength to speak her mind and stand up to her awful relatives. Rebelling against her family, she soon discovers a wonderful new world, full of adventure and love, beyond even her wildest dreams.
