Percy Jackson 4: The Battle of the Labyrinth

Sorry for the long time, but I've been very busy, at least recently.
I've just realised that all the PJ books are very similar and of almost same quality. So yes, it's still good, still funny, still about Percy (no!). Still about Percy and Annabeth, still about Grover's quest, still about Tyson and Chiron and Camp Half Blood, still about Luke and Kronos. I liked it, it'd been a long time since we'd had that desparation to read a book - racing inside to get to it first, bickering over how long it'd been since you'd finished that chapter (we often try to read about a hundred pages/some chapters at a time, so that there's some fairness), staying up late/getting up early to read. It started with HP, actually. Great compliment.
P.S. Have you told you how much I like Riordan's description of centaurs? Mostly centaurs (H.P., Narnia) are described as grave and solemn and learned, I loved his zany, idiotic, 'party ponies' idea.
