Mark of Athena by Rick Riordan
This third book in the Heroes of Olympus series sees two quests undertaken - Annabeth's to search and find the cause and resolve the animosity between the Greeks and the Romans and the assembled demigods efforts to prevent GIA from taking over the world.
The writing was a bit different from previous installments but the story still moved along and captured this reader's imagination.
