"The Lavender Flower" appears to be some kind of romance novel written by Dorothy Rixon. The cover has a woman laying on a bed surrounded by a hundred flowers.
Reading the book has no practical effect, but sometimes floating text will appear over the player: "I feel so strange... but was that her gardener or her best friend's second cousin's brother-in-law? My head hurts." or "That was beautiful... but he didn't deserve her."
