The Last Olympian Book Quiz

1. What does Percy do in the River Styx before the battle? — Bathes to gain the Achilles curse - invulnerable except at one mortal point. With Nico anchoring him below, Percy stands under the current while his mother's memory and Poseidon's beach hold his human tether - he rises invulnerable everywhere except one spot.
2. Whose body does Kronos use to march on New York? — Luke Castellan's, reforged as the titan's host. The traitor of book one carries the titan lord home to Manhattan - and the body still has a will of its own, which is the whole ending.
3. What does Morpheus do to New York before the invasion? — Puts the whole city to sleep so mortals miss the battle. The god of dreams blankets the city - sleepers on the sidewalks, empty avenues, and a battle for Manhattan the mortal world never sees.
4. Which goddess does Percy credit as the real 'last Olympian' of the title? — Hestia, goddess of the hearth, keeper of the flame and of hope. Percy tells Hestia directly that she is the last Olympian and the most important - the hearth survives as embers, and hope survives best at the hearth.
5. Who becomes the new Oracle of Delphi? — Rachel Elizabeth Dare, a mortal with clear sight. The cursed spirit passes to the mortal girl who spent the series proving the Mist is not the only way of seeing - a human voice for the gods' next war.
6. What does Percy do with the gods' offer at the end? — Declines godhood and demands they claim their children by age thirteen. The single choice the prophecy promised: he refuses a throne and spends the wish on the broken system instead - gods must claim their kids, cabins rise for the minor gods and Hades, and the amnesty includes the traitors' children.
7. Which blade ends Kronos - and how? — Annabeth's knife, taken by Luke to stab his own mortal point. The cursed blade of the prophecy is Annabeth's knife - the weapon Luke gave her when she was seven, years before he became the titan's host. Percy gives it back, and Luke, reclaiming his body one last time, does the one thing Kronos cannot survive.
8. What does the Great Prophecy's first line turn out to mean for Percy? — It never names him - the hero of the prophecy is Luke. The prophecy's single choice, the hinge that ends or saves Olympus, is made by Luke, with Percy's hand feeding him the knife. Prophecy parsing, the book's final lesson, is not the same as obedience.
