Super low effort writing, this. Could've been so much more. You do expect Percy to mature but not into a middle-aged man, which is what he sounds like in many places. The beloved Percy Jackson sarcasm has mellowed out, and only shows up a handful of times through the book. The ending is some of the weakest writing I've read in a long while, the chapter breaks are forced and pointless, just bad overall. Pains me to rate a Percy Jackson book anything but five stars.

Was this book just promo for the new series? Seems very much like that. The saving grace is that is not another Cursed Child.
