Sometimes, fun. Other times, tedious. I found the tedium stemming from what I perceived as this need to justify and give the magic system its due diligence because That's Just What Happens In Every Cosmere Book. It was overall touching and genuine. The "action" and magic system was neat, but I don't think Water + Spores = Jack's Beanstalk is robust enough to carry the book upon.

I hate to seem like I'm comparing, but since they were both fresh on my mind, I frequently found it feeling similar to Howl's Moving Castle by Diana Wynne Jones, and to Senlin Ascends/Hand of the Sphinx by Josiah Bancroft. Maybe some Treasure Island too. Good things, all.
