Summary (from Goodreads): Annabeth is terrified. Just when she’s about to be reunited with Percy—after six months of being apart, thanks to Hera—it looks like Camp Jupiter is preparing for war. As Annabeth and her friends Jason, Piper, and Leo fly in on the Argo II, she can’t blame the Roman demigods for thinking the ship is a Greek weapon. With its steaming bronze dragon masthead, Leo’s fantastical creation doesn’t appear friendly. Annabeth hopes that the sight of their praetor Jason on deck will reassure the Romans that the visitors from Camp Half-Blood are coming in peace. And that’s only one of her worries. In her pocket Annabeth carries a gift from her mother that came with an unnerving demand: Follow the Mark of Athena. Avenge me. Annabeth already feels weighed down by the prophecy that will send seven demigods on a quest to find—and close— the Doors of Death. What more does Athena want from her? Annabeth’s biggest fear, though, is that Percy might have changed. What if he’s now attached to Roman ways? Does he still need his old friends? As the daughter of the goddess of war and wisdom, Annabeth knows she was born to be a leader, but never again does she want to be without Seaweed Brain by her side. Narrated by four different demigods, The Mark of Athena is an unforgettable journey across land and sea to Rome, where important discoveries, surprising sacrifices, and unspeakable horrors await. Climb aboard the Argo II, if you dare. . . .
My Summary: It seems as if Annabeth's prayers have finally been answered - they've located Percy, and are on their way to the Roman camp to retrieve him. While they're there, Annabeth and the others hope to solidify their rocky relationship with the rival camp and get their help fighting Gaea before it's too late.
But Gaea has other plans, and instead of creating peace between the camps, Annabeth and her friends accidentally start a war with Camp Jupiter. But that's the least of their worries - if they don't find Hazel's brother Nico before the First of July, he'll die.
Now with Percy and his group in tow, the demigods must find a way to get to Nico and stop Gaea's plan before it's too late - all while fighting against their would-be friends. But can they possibly succeed with the odds stacked against them?
My Thoughts: I just... wow. I finished a while ago, and yet I still can't seem to form completely coherent opinions about this one. Well, I can... kind of. IT WAS SO GOOD! I loved every minute of it - I even bought the ebook version so that I could read it when I wasn't home and had a few spare minutes between classes and such. Every aspect was absolutely wonderful. We got to see a lot of character growth and relationship strengthening, and we also got some revelations about the gods themselves. I, for one, was close to tears after that ending... I mean seriously, talk about a sucker-punch to the feelings! Thanks Mr. Riordan, that was just what I needed today.
Final Thoughts: I definitely recommend checking out the entire series, starting from The Lightning Thief. You will not regret it!
