Final answer:
There is no memo dated September 17th by Lucy in the book 'Dracula' as Lucy's experiences are detailed in journal entries and letters. The provided text actually pertains to a separate story about Lucy Dare, not Lucy Westenra from 'Dracula'.
Step-by-step explanation:
In the book Dracula, there is no memo dated September 17th in which Lucy describes her encounter with Dracula, her daily routine, her future plans, or her favorite book. The passages provided relate to a different story, with characters Lucy Dare in a setting that doesn't connect to the events of Dracula by Bram Stoker. If you're referring to Lucy Westenra from Dracula, she does have journal entries and letters that describe her experience and interactions with Count Dracula and others. These entries detail her illness, her engagement, her friendship with Mina Murray, and ultimately her encounter with Dracula that leads to her becoming one of the undead.
The text provided seems to be from a story about Lucy Dare, a character who is certainly separate from the Lucy in Bram Stoker's Dracula. The detailed memory of an old encounter with Lucy Dare and her fateful choice, impacting the house she inhabited, is highlighted but not related to Lucy Westenra's experiences in Dracula.
