Between Sea and Sky is a sweet romance between a flying boy and a mermaid boy. This reminds me of the scene in Ever After where Danielle asks Davinci "A bird may love a fish, senor, but where will they live?". I may have watched that movie one too many times but the point is that the love story of two people from competing cultures is integral to our collective hearts. Dolamore has a much more literal version then normal but that isn't what makes the story unusual. One is that for the heroine Esmerine it's not Alan that matters, but her lost sister Dosia. The others are in the lovers themselves. Neither of them are perfect, especially Alan. Watching Esmerine bring out the best in Alan was my favorite thing about this novel. In it Dolamore shows a perception of human nature that amazes me. However there were a lot of flaws. Esmerine's search for her sister is rushed over in gestation and anti-climactic in presentation. Everything about this book feels rushed and sugar-coated. So many good ideas are brought up but then not followed through. It's really much more of a novella then a novel. Overall I would read it again but I would be careful who I recommended it too.
