I wanted to make sure that the second book was far more ambitious than the first, allowing the characters to wage their war on a much grander scale than in Olympus Rises. The focus of Olympus Rises was mostly on action; never letting the pace flag. That's mostly unchanged with the sequel, but I wanted to expand several of the side characters, as well as embellish the central characters. Going to try and get a few more thousand words today, so check back for a more in depth blog post later!
