Is it too late to join?. This because I now have option now I've gone on a reactivation spree

Potential ins for this plot:
- character(s) seeking the books for academic reasons, eg they want to know if they really exist and study the magic that created them (of my crew, judy and anthea would fit here)
- character(s) seeking the books for personal/selfish reasons (of my crew, egeria could fit here)
- character(s) seeking the books to contain/destroy them (judy could fit in here because potentially some unspeakable thing could be to collect the books and vault them away)
- character(s) who don't believe in the books, until weird things start happening to te people who are looking for them (anthea could fits, also judy?)
- characters who may have had the books in their possession at one point, or were connected to people who were ~impacted by the book (Egeria fits here. Her family are cursed with alot of bad luck? Perhaps getting the book has caused the downfall of her family and their eventual class drop. Her grandparents and great grandparents live in the ancient family home that has been in their family for centuries (and looks like it). It has a hidden library, a warren of secret passageways, boltholes and closed off rooms. Holding onto the house is one of main reasons they cannot afford the upper-class lifestyle. It is a money pit. But there is sure to be at least one of these books there. Somewhere.
- characters who may or may not believe the books exist but have stories to tell (or embellish) about the books to either lead people down the right track or distract them (possibly Judy. For amusement. Though if it I'd a Department of Mysteries let's contain it thing she potentially would also distract or misleading people for their own safety along with warning then not to
- characters who discover the books haphazardly and are themselves impacted by the spells (possibly Egeria because Egeria has the highest chance of having one lying around.
