Generate a highly detailed and evocative image of a woman deeply engrossed in reading a book by a window. The setting is cozy and intimate, with a dark, rainy atmosphere outside. The woman should have long, flowing hair and be dressed in comfortable, warm clothing, such as a knitted sweater. The window should showcase heavy rain pouring down, with droplets creating a blurred effect, enhancing the sense of isolation and tranquility. The interior should be softly lit, perhaps with the warm glow of a lamp nearby, casting gentle shadows. Include details like scattered books on a nearby table, a steaming cup of tea or coffee, and a plush blanket draped over the woman's legs. The overall mood should convey a sense of calm, reflection, and contentment amidst the stormy weather outside.
