Finished House of Hades and the Dangerous days of Daniel X, Daniel X: Watch the Skies, and Daniel X: Demons and Droids

I finished the House of Hades basically everyone survives but they don't go for battle just yet and that happens in the next book.

Daniel X is a fifteen year old boy. But not just any fifteen year old, an Alien Hunter. His parents' deaths left him with a list of alien criminals that he is to terminate. Twelve years after the murder of his parents, fifteen-year-old alien Daniel X has taken up the task of his parents as Defender of Earth. In the sewers of Portland, Oregon, he defeats number 19 on the List of Alien Outlaws on Earth, Orkng Jllfgna, in hopes of working his way up to number 1: The Prayer. The Prayer was the one who murdered Daniel's parents. Daniel then leaves to go to Los Angeles in search of number 6 on his List, Ergent Seth.Daniel has the power to create with his mind, but must be focused and calm. In the Dangerous Days of Daniel X, he explains, "There's only so much I can create, for a limited period. I have to be really calm, and concentrate like you wouldn't believe. If I'm tired or cranky, forget it—it won't work. Plus there seems to be a mass limit. Or sometimes I seem to run up against a mental block of some kind. One time I tried to create a really cool, flaming red Ferrari, but nothing happened." He can shape shift and read minds, which makes it easier to terminate all the aliens. He is forced to move from town to town because of some laws he has broken, and he must move to wherever the next alien on the list is living. He doesn't go to school, not until the middle of the book, when he moves to LA. He is very smart, but sometimes he acts dumb, just so he doesn't get made fun of or so that he doesn't gain unwanted attention. Daniel is also quite cocky, however, and doesn't always think things through, usually underestimating an opponent or enemy.
