I just finished the book Ocean by David Attenborough and C. Butfield. 5 stars from me. I wish many politicians would read it, as it contains many common-sense and well balanced suggestions for the future of our world's oceans.

Out of the covers you listed, Exile of Water & Gold really stands out.

For me, it was the cover of Emily Wilde's Map of the Otherlands by Heather Fawcett. Really matches the style of an Edwardian lady's journal.
