I read this book because it's by the author of When You Reach Me, which was AMAZING. This author has a knack for writing very subtle science fiction. The setting of this story is in Greenland, and she makes it beautifully vivid. The story moves back and forth between two worlds that exist in nearly the same place, and she writes it so well that I could picture every detail. I would definitely recommend this book, and I'm already looking forward to any future novels that she writes. ( )

It was hard not to think of City of Ember while reading this book. Not in a bad way, just... I kept being reminded of it. There are, after all, many similarities.

I enjoyed this book and will happily recommend it to kids. I will have to warn them, though, that it takes a while for the threads to come together into a cohesive story.

Ultimately, though, I don't think it's as finely crafted as When You Reach Me. I love the idea for this story better than the execution of it. The ice world wasn't as fully or clearly developed as I would have liked, and I thought the plot culmination deteriorated into expository shouting matches. If I were in charge of the world, I'd have liked to get through the first half more quickly, and tease out the second half. Maybe even a multi-generational narrative; I think at least half the story is Mai's. ( )

I've probably said this before but this is one of the best books I've read! I love an edge of your seat book with a twist!!! Highly recommend! ( )

Rather slow to start but devoted fantasy fans may forgive. The idea of global warming threatening a hidden world makes an intriguing mix of real and fantasy. ( )

What an amazing story. Covers so many topics, from family relationships to our environment. I was glued to the story from beginning to end! ( )
