This is really starting to test my mermaid infatuation. I couldn't really get behind the turn the story took (amnesia, ugh) and it really did feel tacked on to extend the lifespan of the series. The romance was getting a little too racy for my tastes, too, especially since I can't really tell how old Lucia is supposed to be. She looks 16-17, but acts much younger. But... mermaids. And there's only two volumes left, so I'll soldier on.
