The Last Olympian

The Last Olympian is about Percy Jackson and his friends trying to save Olympus. 40 kids from Camp Half-Blood go to Manhattan to try to stop Kronos' army.The campers try to stop his army from invading Mount Olympus on the 600th floor of the Empire State Building. But, across the country, the All-powerful Titan, Typhon, is being stopped by the gods of Olympus. This book is over 300 pages, so it will count as 2 books in your 25 Book List. It is a great read and I recommend it. But, I do not recommend reading it before you have read the first 4.
