Grimoires and Green Tea

What do you do with a grumpy grimoire?
When Sibyl unexpectedly acquires a magical bookshop, she's torn between exhilaration and panic. She's landed on her feet on her first venture away from home: the bookshop comes complete with an apartment above it. But as her would-be customers press her for an opening date, she has to juggle cataloguing the books and trying to keep her new apartment rodent-free - not to mention settling the unruly grimoire her benefactors left her. Plus, there's a vampire intent on gaining entry.
With no experience in retail and a grumpy grimoire to keep in check, will she ever succeed in running a bookshop?
