The End of Olympus (Pegasus Book 6)

the final Pegasus book takes things to greater extremes. It is now the universe that may be in danger. There are mutant titans that suck power. The only way they are defeated in the end is by having them suck too much power. In between, the goodguys go Wandering Earth and move a planet.

The book is a showcase for modern individualistic values. Don't let a single person get harmed,e harmed, even if that means saving millions. After all, there will end up being some way to magically save those millions after all. In the end Emily becomes deified and somehow makes some big sacrifice that doesn't seem to be a sacrifice at all.
