In honor of Apollo let me try writing a haiku to describe the plot of this book: 
 Apollo's so bi 
 Lesbians rescue their kid 
 We are very blessed 
 Aren't I so talented? Seriously though I love that every chapter has a ridiculous haiku at the beginning. And I love these books, they're just fun. Like I see a lot of people complain that they dumb down / change the myths too much or that they're too ridiculous but like A) they're for children and B-Z) why do you hate fun? Anyway I absolutely love Apollo, he was always my favorite god in the PJO series so I love that he's got his own series now. And I love how he's so bi that he spends half the book flashing back to how he used to date the guy they're supposed to be fighting. Amazing. Also love that we get to meet ex-Hunters of Artemis who are in a happy relationship with an adopted daughter. And Leo and Calypso and MEG! I love Meg. Also yay for having something set in Indiana that isn't a horror movie / Supernatural episode ;) 
 Although there was a reveal about the Hunters that I'm kind of ehhh about: (view spoiler)[like it says that Artemis doesn't allow any romantic relationships in the hunters and I get that Rick did that to make all the hunters aro/ace and I appreciate the effort but like ...obviously they AREN'T because at least two of them fell in love and had to leave the hunters to be together. So it's more like Artemis herself is aro/ace and then she forces that on her hunters, which is really not cool. And this is coming from an aro/ace person who is like literally starved for representation in that area (hide spoiler)]. Maybe it's something he will expand on / make a bit better in later books though. If there's one thing Rick is good at it's listening to constructive criticism and realizing that no matter how far he's come he can always do better when it comes to representation.
