This book was fantastic. The setup is that shapeshifting, people-eating, amorphous blob Shesheshen is rescued by overly kind Homily, believing Shesheshen to be a person. Ironically, Homily comes from a monstrously toxic family of wyrm hunters, who are all out to kill Shesheshen specifically, while not realizing that Shesheshen is said monster. (Hijinks ensue.)

It's a story that deals with passing and masking--Shesheshen works really hard at trying to be a person, physically and socially assembled from what she can scavenge. She's got a wry non-human perspective that's especially biology-focused, like how to form legs and have a humanish shape, the tricky mechanics of eating with your mouth closed, and the overwhelmingness of smells and noises.

This book also deals with physically and emotionally abusive family, and how hard it is to struggle through trauma, no matter how much you are being hurt. Also, as you might expect, this book is also about family and royalty being the true monsters.

Normally, I am not keen on stories where a good bit of relationship tension comes from an intentional deception leading up to an eventual awkward reveal. Even if you ignore the self-protective reasons here, I think the setup in this book works partially for comedy reasons, as Shesheshen considers devouring Homily at the outset, but as she gets more entangled in Homily's family life, it also works as a deception told for protective reasons. It narratively worked for me enough to not be feeling "just tell her already!" throughout the book. The fact that there are a number of worse deceptions elsewhere also makes this feel more minor than you'd imagine it could be.

I devoured (pun not intended) the whole book in one day. Strong recommend from me.
