The Mark of Athena question

I read this series earlier this year. It was great. Ive also read pjo, the Kane chronicles, and Magnus chase. I’d recommend to skip Magnus chase though; it wasn’t that great.

I was reading this book series earlier. I did read Camp Half Blood and Heroes of Olympus series. They are really amazing. I loved it. Haven't completed the Kane Chronicles though.

I have read the first 4 books, but my library doesn't have the last book. I don't want to purchase the whole series and especially not the last book. So I am not sure what I should do, but I absolutely love the books that I read.

I read the whole series and I loved it!! But the ending of the last book was in a bit of haste... I've started the Kane Chronicles and it seems great!!
