The House of Hades by Rick Riordan
At the end of the last installment, Percy and Annabeth get caught in a giant web which pulls them through an opening and they fall into Tartarus, used as a dungeon of torment and suffering and prison for numerous monsters. To survive, Annabeth and Percy must make their way through the abyss to the Doors of Death where hopefully their friends will be waiting to free them.
Percy and Annabeth's encounters in the abyss are filled with danger frequently offset by amusing interactions with monsters that aren't all bad.
Meanwhile, above, the remaining quest members are encountering their own monster problems trying to reach the Doors of Death on their side (first they have to figure where that would be.)
The story was fun and full of action - will definitely have to read the last SOON!
