Ink Blood Sister Scribe is a standalone novel about magical books, families, and secrets. Overall, this was just a fun ride. Plenty of action, fun worldbuilding reveals, good foreshadowing but also a few reveals I didn't see coming.

The three main characters that it follows all are sort of trapped in their own way by their family. Joanna (who can hear magic), is trapped protecting her family's magic book collection after her dad has died. Her estranged half-sister Esther is trapped on the run, following (until she doesn't, kicking off the plot) her dad's wishes that she move every year on November 2nd so that her mom's killers don't catch up with her. Nicholas is trapped by his overbearing father and his assistant Maram for his own safety after several attacks. They all in some way work towards their own freedom and untangle secrets about the past and each other.

I enjoyed the magic system in this book a lot. Magic in this world has a cost (sometimes people's lives) to create magic books (as the title might imply), doesn't come with infinite uses, and often has a short time limit on how long the spell lasts when read. I enjoy that the success of the creation process is largely vibes-based, in that (for example) to create a better book with a truth-spell one needs to obtain accoutrement to recreate a similar context where they personally felt great truths being told. There's also an in-world reason why book magic is bloodline-related.
