However, if you haven't read Age of the Ashers yet, then I would highly recommend you start here. Why? Because this book is near perfect, and it will help to understand the underlying political and social paradigms that the world of Petros is embroiled in for Age of the Ashers. Many of the concepts of that book which were not entirely clear at first would have been much clearer had I started with this book.
The story in Moonbow starts with a brief Prologue that describes the backstory of the world Iris was born into. As the first chapter opens, we learn that Iris has just lost her brother, who had just been executed, though the reason for his execution isn't clear at first. Iris responds by losing her composure and leaping into the ice-cold water in which her brother's funeral boat is to be set aflame and passes out. She is awakened the next morning by Niobe, who, like Iris, is a slave of Acheron. It was by Acheron's command that her brother had been executed, and it is the desire of Iris to avenge her brother's death that places her feet on the journey she engages through the rest of the book.
Also, like Age of the Ashers, this book is filled with references to the early Greek Gods, though these Gods and mythical creatures, other than a few, are more supporting characters than they are in Age of the Ashers. Still, Anderson-Tyler seems to have done her homework when it comes to depicting the Gods and what their personalities would most likely have been like had they actually been real beings. Anderson-Tyler also does a fabulous job with the word-crafting throughout, using extremely uncommon synonyms for a good number of commonly used words, a few of which, I'll admit, I had to look up. And though I am usually not a fan of flowery language or authors who over-use the thesaurus as a writing tool, for this book, it really worked. I could imagine the characters speaking just as Anderson-Tyler wrote, and the flowery tone of the text truly matched what I would consider the environment of this fictional world to have been.
Bottom line, another 4+ star review for a wonderfully written and incredibly entertaining novel.
