phenomen a book

Selen Moonlit had hoped death wouldn''''t be the end for her, but never expected it to come so soon -- or for her salvation to come in such a strange way. Given the chance to take over for someone who would''''ve died in another world, she picked the life of a young bird-girl. Now she lives in the post office of a river city lit by crystals, and her adoptive family wants to know what classes and statistics she wants to develop. She knows enough about games to guess how this kind of rule system works. But she used to be an aspiring chemist with a good knowledge of other science. All alone in an unfamiliar world, yet surrounded by family she barely knows, what can she do to make this new life meaningful?
