Done 2 (not really actually)

Last year I made a similar post like this when I talked about my opinion on the Son of Neptune.
Lately I've been reading the Mark of Athena which is the third and latest book of the series. I waited a year for it to come out, then one month for the book to arrive while all my friends read it and shoved the book to my face.
Then one day I got it. I got the book.
I felt its velvety cover and appreciated its holiness, but I didn't read it. I didn't have the time!
The maximum amount of days I take reading a book I have been waiting for is 4. 4.
I have been reading this book for a month.
I blame the copious amount of unnecessary homework and piled up exams, and the general frustration literally every page of the book brought me as I died in annoyance and boredom.
I'm still not done, but I have about 2 chapters left.
Now to start off, I was extremely excited about this book when I ordered it. When I actually got it? Not so much. Sure I read a few chapters in the first day, but then something happened and I forgot about it.
I read the second half of the book in 2 days though.
What does this mean? First half puts you to sleep, second half is a little too exciting.
I loved the Son of Neptune, but this book really disappointed me.
I mean, there were so many logic obliterations (that's what I like to call it) that instead of enjoying the miracles or the fact that they can cross the ocean in half a day without any jet lag whatsoever and jump up ready to go off on an adventure I was complaining to myself.
Two of the characters I despised. I know I should not be hating my half brother, but Jason son of Zeus/Jupiter (I support the Greek side honestly) is just made to be hated. He is overpowered, too perfect, and still can't do anything at all.  Rick Riordan made me dislike my favorite character too.
Also, since I did not like a lot of the characters, when I learned that one of my favorite characters from the old series was going to make an appearance, I was literally rolling on the floor, jumping up and down, squealing and yelling to my friend about it. I also drew about 10 drawings of him. Nico di Angelo, son of Hades, he is awesome.
But you know what? All this waiting has ended in some sort of disappointment too.
The only thing Nico did so far was crawl between giants' legs, get teleported by Bacchus, and then croak thanks and apologies.
And I am angry with Rick Riordan for seriously copying every idea we had about our fanfiction in 7th grade. Seriously, there are too many similarities to be called a coincidence. I think he's been reading our Skype conversations for inspiration.
I think the book progressed way too quickly and too slowly and it had too many things going on at once that I actually had to put it down and be like "I am not reading you until my brain can register what is happening around me."
And it's going to end. And I spoiled the ending for myself a long time ago. So I'm not very pleased with anything. Nope nope nope nope.


Or maybe I'm just growing up.
