The rest of the plot wasn't for me, or I just didn't have enough brain to keep track of the missing jade, and the mummies, and the visions, and the possessed shapechanging dragon, and there was more than that. I also never am very fond of the "childhood friends separated by fate" plot, which also figured into this. I felt like the plot took up too much of the story. Weird complaint about a romance, right? Usually having a plot makes it better. But I was just not in the mood for that.
I wanted Dean and Miri in a different story. I wouldn't have missed the dragons at all, and especially not the jade and the teleporting and the visions from the past. If I read this again, I'll probably just go for certain scenes.
