my favorite book is TheMark of Athena. I like

the Mark of Athena because it had a lot of action in it and a lot of adventure to it. it also had a lot of times when just in the nick of time someone saved someone. and I also liked it because most endings end good this ending ended somewhat maybe good or bad but i’m not going to tell you how the Mark of Athena ends P.S (I hope you read the other two books called The Lost Hero and The Son of Neptune and if you are a fan of this series like i am i hope you are going to read the next book called The House of Hades
