Goodreads summary:

IT'S NOT EVERYDAY YOU FIND YOURSELF IN COMBAT WITH A HALF-LION, HALF-HUMAN.

But when you're the son of a Greek god, it happens. And now my friend Annabeth is missing, a goddess is in chains and only five half-blood heroes can join the quest to defeat the doomsday monster.

Oh and guess what. The Oracle has predicted that not all of us will survive...

My opinion:

I really liked this book (for some reason, I don't know why) more than the first two books in this series and I appreciate it more and more. The story is just so complex, because there are so many storylines and mythology background that is linked with each other. I also love the friendship moral in this one (even though this also happens in the first two books). I'm glad I picked it up after all. 

What is your opinion about the third book in this series?

So this is going to happen again! Usually I can't participate because of school or other things, but now I can.

It will take place in the April 23rd (as you can see), but it starts at a different timezone for everyone. I live in the Amsterdam timezone, which means I will be starting at 2pm (on Saturday). I will try to post an update each hour (try, not making a promise here and of course not when I'm sleeping). I'm going to post on my Twitter, so click here if you don't follow me already. These are the books I plan to read: 

I think it's manageable and quick reads (and not too challenging) so I really hope I can get to these. If you want to join as well you can follow the original Twitter account (klick here) for sprints and use the hashtag #readathon to chat along. 

Are you going to join and if so what's on your tbr?
