I absolutely loved this book - definitely one of the best I've read this year!
I thought it was so well written - the language and vocabulary were just right for the era and it rang true all the way through. And I thought the characters were so well drawn. I liked both the Forresters a lot and I liked the way we got to know their characters and stories through their letters and diaries in a slow unfolding where, as readers, we could draw our own conclusions - we weren't being told how to think and feel. The story of the growing friendship between Walter and Josh through their letters and through sharing the papers was well done and I thought it was a clever way of showing the reader what that initial explorations set in motion.
The mythology aspects were interesting too - I liked how the magical events were just presented as they were experienced. There was no attempt to explain them away and go over and over them, just the facts as they were experienced. They challenged Allen's view of his world and I liked how he accepted them and could entertain the idea that maybe his beliefs weren't the only ones.
I just found it such a satisfying read with so much more going on than just the story of the exploration of the river. I thought the structure of the book worked so well and including the sketches, photos, illustrations from old books and cards etc just added to the richness of the experience of reading it.
Really looking forward to hearing what others think of it.
