I liked the changes to the story that you made in Thorn. Having Embla sick is a great way of establishing stakes and giving Prue agency. The setting sounded interesting, solid names. The voice was a little sparse for me, but by no means bad. I would've preferred more figurative language.
The dialogue between Prue and Embla was great. I liked the back and forth and it felt authentic to that kind of experience. Prue's frustration is honest, Embla's desire for control is on display and that feels right for a family.
I wish I had the funds to check the book out in its entirety. What are you working on right now?
