on which book do you think rick riordan's writing started to decline? [general]
while we are all fans of his works, it's undeniable that he isn't as great of a writer as he used to be.
for me, it was somewhere in heroes of olympus. i remember characters like percy and annabeth being OOC there vs in the original series, and i'm NOT talking about the change in POV from first person to third person. blood of olympus was outright terrible.
