"Run Posy Run" by Cate C. Wells appears to be a romance novel. After conducting a thorough search, I found that the book is indeed available in various formats, including EPUB and PDF.
After Dario believes a doctored video suggests Posy cheated on him, he ruthlessly casts her out. Understanding the danger she is in without his protection, Posy flees.
