From time to time, readers email me to say they are unhappy with the ending of The Book of Dreams because it isn't clear what Dana and Jean choose to do at the end. Now I'm not calling anyone thick, because you couldn't possibly read a 700 page book if you were, but I do have to say there's a failure to think here. (I blame television.) All the clues are right there in the Postscript:
1) It's a year and a day later. Throughout the series it is repeated that a year and a day is the time period for ending a spell or enchantment. Ok, that one is subtle and could be missed.
2) Grandfather won't go to bed and is gazing out the window into the night as if he's expecting visitors. Ok, this could be cancelled out by Roy saying they've made their choice, we've got to let them go, but who's the medicine man here and knows more than everyone else in the book? Yes, Grandfather.
3) Roy has a dream that he's playing soccer in the Northern Lights with Jean and Dana and then he plummets out of the sky, like a falling star. "Did the others fall with him?" asks the book. Ok, I don't answer the question, but doesn't asking it give a pretty big hint?
4) Finally - and could this be more obvious? - Roy wakes up to the sound of voices talking and laughing outside, feet crunching on the snow, and then a knock on the door. Ok, you could argue this might be two Mormons or the Avon Lady, but then why is Roy jumping out of bed, pulling on his jeans and yelling with excitement? Hmm?
A failure to think, that's what it is. To quote my beloved CS Lewis's Professor Digory, "I wonder what they do teach them at these schools." (Photo credit: Wolf Summer, Norwegian film)
