Query: Blissful Escape

So much has already been said, it's hard to know what to add. Everyone's personal experience with a book is different. Our opinions can be shaped by so many different factors. For me, this book was an escape when I desperately needed one. No long sob story is needed: I spent my summer traveling back and forth to the University of Michigan Hospital in Ann Arbor. I have something called a brain AVM, and we had to figure out what to do about it. I had lots of tests, some of them...uncomfortable. Whenever I could read A Breath of Snow and Ashes, I escaped from all the stress and worry. Words cannot express how much I enjoyed this book, and how much I cherish this series.
