MAJOR SPOILERS NO LIE. ALL ABOUT EVERY PJO/HOO BOOK ALIVE! This is set after all of the books, except for Trials of Apollo. I have read both books, but I don't feel like reminding myself of the timeline. Some pieces of the ToA timeline are present, like Calypso and Solangelo. Jasper, Frazel, Caleo, Solangelo, and Gruniper are all present. Leo also made monster proof phones, so no complaining about the no-technology rule. The book is only in Annabeth's POV. If there are any plot holes or spelling errors, please ignore. I am horrible at typing accurately, and I haven't read the first series in a while. I have re-read the second series more than I want to admit, though.
