A series of young adult fantasy novels written by Thomas E. Sniegoski, '''''The Fallen''''' tells the story of Aaron Corbet, an OrdinaryHighSchoolStudent who, on his [[DangerousSixteenthBirthday eighteenth birthday]], begins developing strange abilities. He soon learns that he is a {{Nephilim}}, the [[HumanMomNonhumanDad offspring of an angel and a human woman]]. Also, as it turns out, Aaron isn't just any ordinary Nephilim; according to an ancient prophecy, he is the [[TheChosenOne Redeemer]], the only Nephilim with the power to absolve the sins of {{Fallen Angel}}s and send them back to {{Heaven}}.

When [[BigBad Verchiel]], the leader of the Powers (warrior angels charged with wiping out all Nephilim), kills his foster parents and kidnaps his autistic younger foster brother Stevie, Aaron is forced to leave his hometown with Camael, the former leader of the Powers who believes in the prophecy of the Redeemer and becomes Aaron's [[{{Mentors}} Mentor]], and his pet dog Gabriel whom Aaron can talk to after the latter heals him.

The series consists of seven books:

* ''The Fallen'' (released 2003)
* ''Leviathan'' (released 2003)
* ''Aerie'' (released 2003)
* ''Reckoning'' (released 2004)
* ''End of Days'' (released 2011)
* ''Forsaken'' (released 2012)
* ''Armageddon'' (released 2013)

In 2006, ''The Fallen'' was adapted into a miniseries that aired on ABC Family.

* {{Satan}}: [[spoiler:In this series, Satan and Lucifer are separate entities. Satan is one of many {{Eldritch Abomination}}s that existed before {{God}} commanded "Let there be light"; once the Creator called forth light, Satan and his fellow monsters were forced into hiding in the shadows until after the events of ''Reckoning''. Starting with ''End of Days'', Satan takes Verchiel's place as the new BigBad. He assumes the form of a [[CreepyChild creepy little boy]] to speak with Lucifer (whom he encountered before in the past) about his plans for the oncoming [[TheEndOfTheWorldAsWeKnowIt end of the world]]. Later on, Satan [[DemonicPossession takes possession]] of Lucifer's body. No, seriously, he does]].
* [[spoiler:SatanIsGood: While Lucifer has committed many horrible deeds in the past, this is explained as because of his jealousy towards humans. He believed he was no longer loved by God when God created humanity, which is why he rebelled against Him. During the time frame in which ''The Fallen'' takes place, though, it is shown that he deeply regrets his past actions and now seeks redemption; he is also shown in his first appearance to have been serving as a priest in a church and has befriended a small mouse he names "[[ParadiseLost Milton]]." He is also Aaron's father. Though in the end, God still has not forgiven him; it is heavily suggested that it is merely a matter of time at this point. Also, {{Hell}} is not a place where Lucifer tortures the souls of evildoers, but rather his own tormented metaphysical state of being caused by all of the grief of the heavenly war being sealed into his body.]]
* ShootTheDog: [[spoiler:In ''Reckoning'', Aaron is forced to kill Stevie/Malak]].
* WouldHurtAChild: [[spoiler:Verchiel kidnaps Stevie, Aaron's autistic foster brother, and uses ancient magic to transform the poor boy into a lethal killing machine by the name of ''Malak''.]]
