At the conclusion of The Mark of Athena, Annabeth and Percy tumble into a pit leading straight to the Underworld. The other five demigods have to put aside their grief and follow Percy’s instructions to find the mortal side of the Doors of Death. If they can fight their way through Gaea’s forces, and Percy and Annabeth can survive the House of Hades, then the Seven will be able to seal the Doors both sides and prevent the giants from raising Gaea. But, Leo wonders, if the Doors are sealed, how will Percy and Annabeth be able to escape?
They have no choice. If the demigods don’t succeed, Gaea’s armies will never die. They have no time. In about a month, the Romans will march on Camp Half-Blood. The stakes are higher than ever in this adventure that dives into the depths of Tartarus.
4/5 stars (really liked it)
This book starts out right where the last one left off. Percy and Annabeth have just fallen into Tartarus and must survive and make it to the Doors of Death. Leo, Hazel, Frank, Jason, Piper and Nico are on the Argo II with the statue of Athena and must also make it to the Doors of Death. It seems that in this book a lot of the characters overcame an obstacle or faced a fear. Nico faced one of his biggest fears and had an unexpected person witness it. Frank also faced a big obstacle. I like how the book was told in several points of view so you really got an idea of what was going on all around. We even find out some surprising things about Coach Hedge. I did miss the lack of Grover and Tyson in this book and hope they are in the next book more. Seems like a lot of the major battles will be fought in the next book.
