>>149167695I read every book in the Camp Half-Blood quintent probably five times each at least and I followed the sequel series for the first two books, as well as the first spin-off with the Egyptian kids. I've revisited the first three books so far and I think The Lightning Thief is the strongest, although I remember feeling fondly about The Battle Of The Labyrinth especially. I don't remember anything about The Last Olympian.
For me, seeing Riordan tard out last decade made me feel like my waning interest was warranted. Part of the original conceit of the books was that weird kids who were slapped with psych diagnoses and hurled into the tard pipeline of the Northeast school system were actually demigods who were better than their abusers because they were connected to an ages-old mythological happening much deeper and more exciting than the mundane world, and that they were victims of a conspiracy. Percy's lines about feeling shame being in a special ed school say anything I could about my own history here (you might recall that Andrew almost had the same problem). Riordan turning into a vitriolic social justice bully was a complete betrayal and I have no reason to return to the books beyond a certain point now.
Fowl has at least four great books (I would say 4 > 3 > 1 > 2), but I didn't dislike anything in the second half of the series aside from The Last Guardian, and even that had a great intro and a great ending. Artemis is a stronger character than any of the half-blood kids because he's an actual villain and he's a super-intelligent character written in a way that he was actually admirable and impressive to me as a child genius. I have no idea what your perspective on villains is, but if you're here, maybe you're cool enough to give him another shot someday.
