I’m currently reading The Gospel of Loki by Joanne M. Harris. There are a couple things I love about this book: the mythology, the narrator, the cover. My favourite parts are the brief Loki quotes at the beginning of each chapter, which add some well loved humour.
A quick read, never to dense or meandering like more traditionally written myths can be, this book is full or quick dialogue, beautiful description, and as mentioned earlier, humour. If you love mythology, as I do, then this is a book for you.
