I finished reading the book the same day I got it. I was lucky to find a copy since when I went to Walmart there were all out but luckily I found a hidden one in the children's coloring book section (sorry to whoever hid it there). It was an awesome and well written conclusion to the series. MAJOR SPOILER HERE SO BE WARNED!!!!! When I was reading I read about Chiron's secret meeting with a severed head (possibly Mimir from Magnus Chase???) and a cat (Bast from Kane Chronicles????). If my boi Rick gives me a crossover with Percy, the Kane siblings, and Magnus Chase, I am legit going to have a heart attack. Please let that be the case.
