Lovely fantasy adventure, totally engrossing. I do wish that the interpersonal dynamics between the children had been explored more thoroughly, they are all set up for it but just...don't have the necessary conversations. I also wish that the tension between Alma and her parents had been better resolved, though perhaps it was more realistic to leave it messy. There was the (fairly common in fantasy) possibility that this "growing the light" was going to veer too close to religion for my taste, but it stayed just on this side of secular, and that was nice. On the whole, totally looking forward to reading more by Jess Redman.
