History Literature / MassEffectDeception

The novel is the only ''Mass Effect'' book to not be written by Creator/DrewKarpyshyn and contains many continuity errors.

* CanonDiscontinuity: The continuity errors and poor reception of the original editions were acknowledged by the publisher and BioWare, who promised a rewrite to replace it in the continuity.

* CanonDiscontinuity: At least the original editions, which a rewrite will replace in the continuity.

* EnemyEatsYourLunch: Kei Lang eats Anderson's cereal while planting a bug in the latter's house.
* EvilIsPetty: As noted above, Kai Leng eats Anderson's cereal.

* ThatMakesMeFeelAngry: A great deal of criticism has been focused upon the author's inability to write characters in a natural manner.

* TooDumbToLive: Let's say that Hendel is very lucky to be alive after he make the huge stupidity of attacking ''Aria friggin T'Loak''.

* CruelAndUnusualDeath: [[Gillian is mortally injured by Kai Leng, when he stabs her InTheBack with a toothbrush.]]
* CuttingOffTheBranches: The Citadel Council in ''Deception'' are made up of an asari, a turian, a salarian and a human. Thus, the playthrough where a Renegade Shepard sacrifices the ''Destiny Ascension'', making Udina appoint an all-human Council (as opposed to a still-mixed-species Council for a Paragon Shepard) is invalidated. ''VideoGame/MassEffect3'' later confirmed this, as there is no all-human Council in it, either, unless it abdicated between the games. Notably the human councilor is ''not'' identified as Udina despite ''Retribution'' implying otherwise, but his actions and personality identify him clearly as such. Nobody's sure why the author didn't name him.

* DownerEnding: [[spoiler:Gillian, Nick, and Hendel all [[DroppedABridgeOnHim die pointless deaths]], Kai Leng gets away again, the Illusive Man is building an ''army'' of Grayson clones (or something possibly ''worse'') and once again the Council sticks their heads in the sand and ignores Kahlee and Anderson's evidence about the Reapers.]]

* BuryYourGays: A previously established homosexual male character [[SuddenlySexuality is turned straight]] before he's killed off.

* KarmaHoudini: [[spoiler:Kai Leng, natch. Gotta keep him alive for ''Mass Effect 3'', after all. Don't worry, Shepard will [[ImpaledWithExtremePrejudice give him what's coming to him]].]]

* IGaveMyWord: After one of Aria's banks is hit by the Grim Skulls, she lets one of their captured mercenaries go after the merc tells Aria who really killed her daughter. When Aria later confronts the same merc in the Grim Skulls' medical bay, she has her transferred to a hospital, her reason being this.

* TheMole: [[spoiler:Cory Kim, ex-partner to Kai Leng, is a deep undercover Ceberus operator in the Biotic Underground. Her cover story is that she quit Cerberus before joining up with the Underground, which even Kai Leng believed at first.]]

%%* WoobieDestroyerOfWorlds: Gillian.

** See [[https://docs.google.com/document/d/1XBpMF3ONlI308D9IGG8KICBHfWKU0sXh0ntukv-_cmo/preview?pli=1&sle=true here]]. Long story short, the novel makes ''many'' errors regarding the lore of the ''Mass Effect'' universe.
** See the Internet Backdraft section on the YMMV page, but [=BioWare=] announced that a revision is coming to correct the many, many errors.

* DroppedABridgeOnHim: [[spoiler:Gillian, Nick, and Hendel]], as noted above.

'''''Mass Effect: Deception''''' is a novel written by William C. Dietz set in the ''Franchise/MassEffect'' universe. It chronicles Gillian Grayson's attempt to avenge her father's death at the hands of Cerberus in ''Literature/MassEffectRetribution''.

* {{Badass}}: Kai Leng takes this to absurd levels. [[spoiler:He kills the most powerful human biotic in the galaxy ''[[ImprovisedWeapon with a toothbrush]]''. Keep in mind that Kai Leng is a completely normal human (at least relatively so) who just had both of his legs shot, and has to move around with a cane.]] Speaking of which, he also kills a guy with a jump kick, even though it's previously established that he's crippled.

* ChronicBackstabbingDisorder: Kai Leng gets two mercenaries to help him steal Grayson's body. He traps one of them in a containment device to act as a decoy, prompting the other {{genre savvy}} merc to demand payment up front. He complies and kills that merc a few hours later.

* IdiotBall: After already losing Nick on the Citadel, Kahlee decides it would be a good idea to let an emotionally unstable Gillian go outside for a spot of fresh air after she's announced her intentions to kill the Illusive Man. Three seconds later she's missing too. The novel does point out this was incredibly stupid thinking on Kahlee's part.
** Aria uses next to none of the security she used in previous books/the second game. Luckily for her, Kai Leng has forgotten about the advanced tactics he used in previous novels as well.
