Dead of Knight: Stories From the Spirit Caller Series - Spirit Caller, #7

Tea and Seal Meat: History talks way too much when you can hear spirits. Table for One: Valetine's Day isn't supposed to be this stressful. Errands Day: Mrs. Saunders needs help running a few errands. DEAD OF KNIGHT: A Spirit Caller Universe Story Lisa Fudge had been the girl-done-right. She'd moved away from home, as did most people her age, and had made a name and a life for herself on the mainland.
However, sickness struck and Lisa moved back home to care for her ailing mother. She spent her savings on an RV and a local business, as both were good investments. Of course, no one plans for a pandemic. Living in her business' parking lot (since she'd lost her apartment), book sales through the basement (which had been why she could even afford anything before), and now an orphan, Lisa struggles to keep her store afloat, her books written, and her dogs fed.
Then, a mysterious man shows up and asks if she's renting out storage space. She needed the money and tried not to think about going to jail for storing drugs. However, when one of the packages starts talking to her, Lisa realized storing drugs would have been preferable.
