"Heroes of Olympus: The House of Hades"
By Rick Riordan.
I rate this book: 5/5
"Heroes of Olympus: House of Hades" is the fourth installment to the never-ending adventures of the Chosen Seven - Percy Jackson, Annabeth Chase, Piper McLean, Jason Grace, Leo Valdez, Frank Zhang and Hazel Levesque. The quest to stop the forces of Gaea and to close the Doors of Death continues, but plans change all of a sudden; now Percy and Annabeth find themselves in the gruesome, unholy depths of Tartarus. The rest are still on Earth, but monsters still lurk around, waiting to strike.
The Seven, accompanied with Nico di Angelo and Coach Hedge, have changed tactics; they plan to close the Doors of Death once and for all - Percy and Annabeth shall search and close them from within Tartarus, and the rest shall make their way through the House of Hades and shall close them from outside - and save Percy and Annabeth. That's enough on their plate already; not to mention Gaea's forces around them, waiting to kill them in any given moment.
No pressure.
