What do you do with a grumpy grimoire?

When Sibyl unexpectedly acquires a magical bookshop, she is torn between exhilaration and panic. She's landed on her feet on her first venture away from home, as 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?
