The Blue Castle: a novel [EPUB ebook] 

29-year-old Valancy Stirling is single and has never been in a relationship. The “forbidden” writings of John Foster and her daydreams of the Blue Castle—a paradise where all her wishes come true and she may be who she genuinely wants to be—are the only solace she can find while living with her controlling mother and meddling aunt. She rebels against her family and discovers an unexpected new world full of love and experiences far beyond her most secret dreams after receiving shocking news from the doctor.
