Factual error: During Soneji's trial in part four, the prosecuting attorney objects when the defense asks Cross a leading question. Since Cross was called by the defense as a hostile witness, it is legally permitted to ask him leading questions.
Factual error: The geographical issues begin about mid-way through with the characters at Glacier National Park in Montana for a wedding. When everyone begins to leave, Nick is taking the scenic route back to New York via car. Harper is getting a ride to South Dakota to catch a plane. The scenic route in Montana is Hwy 2, which the author labels as US Route 2 (technically correct but Montanans call it Hwy 2). Continually talks about 2 lane roads. Yet the next location the car stops at is Sleeping Elk. Higgins has them spending the night there. Sleeping Elk is a smaller than small town that is by the Interstate which entails getting off another Interstate to make the connection. Sleeping Elk has no motels and is less than 10 minutes from Bozeman. Higgins makes it sound like they are in the middle of nowhere when in reality, they are not. Also never mentions the passing by of other large cities including the state capital but rather mentions the smaller cities that are on Hwy 2.
Continuity mistake: About halfway through chapter 12, when they are walking back up the lane after Grimma attacked the fox, Sacco says a couple of sentences - Sacco is at the quarry.
Plot hole: It is revealed in the book that Melancholia's reflection is killed instead of Melancholia to cover their tracks. But reflections are frequently described in the book to be able to be spotted by sorcerers "a mile off." And yet not one Sanctuary Agent or the cleanup crew notice and alert the Sanctuary or Skulduggery.
Other mistake: In the Freddie Fear comic near the end, all of the speech bubbles in the last page of the story are missing, even though it's obvious that people are talking.
Factual error: In chapter 9, 1941 during world war II, Chuck Dewar is stationed in Hawaii where he windsurfs, although windsurfing was first invented 20 years later (in the 60s).
Factual error: During the murder trial in part three, when a prosecution witness of Yuki's is called back to testify for the defense, he is sworn in. But having already testified, he wouldn't have to be sworn in a second time; the presiding judge could simply remind him that he is still under oath.
Continuity mistake: In section 12 of chapter 11, Henry thinks about how "He, Pete, Beaver and Jonesy's wife had kept a secret among them", that Jonesy's "heart had stopped twice" after he was hit by a car about 10 months earlier. This is a mistake because earlier that day, in section 8 of chapter 3, Pete hadn't known about it - Henry tells Pete that Jonesy's "heart stopped in the ambulance", and Pete is shocked to hear it.
Continuity mistake: In The Bridal Dance and And About Time Too, Will checks himself in the mirror, although later it says he can't afford one.
Factual error: On page 512, line 10, there is a mistake in the "voice over" when dealing with the killing of Desi, "the feel of his own blood spurting between his fingers with each pulse." The jugular vein was cut, and veins don't spurt with each pulse; they ooze. Arteries do the spurting with each pulse.
Plot hole: In chapter 19, while talking about Leah Rose, it is stated "She and Rayford had spotted the seal of the believer. Otherwise she might have never given him the time of day." Fact is, when she is introduced in the series, it is Buck whom she meets and they notice the mark of the believer on each other's forehead. When she meets Rayford much later, they both already know each are believers.
Factual error: The main character, a WWI U-boat captain, mentions his vessel as having chemical air regenerators, an underwater airlock for divers to leave by, and of course dive suit(s), but I don't believe such craft of that era had any of those.
Continuity mistake: In chapter 16, Shardlake takes the alchemy books out of his satchel along with the bottle and places them on the table. A few paragraphs later, he once again takes them out of his satchel and lays them on the table.
Plot hole: In the 8th Wizard Of Oz book titled Tik-Tok Of Oz, the group runs into Polychrome, the rainbow's daughter. Polychrome and Shaggy Man first met up in book #5 titled The Road To Oz. However in this book, Shaggy Man and Polychrome act as if it is the 1st time they ever met each other. They make no mention of them meeting before in the prior book.
Other mistake: On page 170, when Quentin is at breakfast and Poppy joins them and we learn she's from Australia the text reads "if that was true he could why see Poppy had gotten the hell out." It should say "see why."
Plot hole: It took Ender only a few hours to unravel a mystery that 3 generations of highly educated and skilled xenologists and xenobiologists were unable to do. Pipo, of the first generation, was restricted by the rules imposed on him by the congress and he found out the truth but died because of it. After that Libo should have simply asked the piggies what happened and should have digged into the piggies' reproduction system, like he should have done in the first place as that is his job. Both Libo and Miro and Ouanda broke the rules so they shouldn't have had a problem with asking the right questions. They weren't afraid of the piggies either, loved them even. Libo would have had the answer to the reason for the death of his father and understood the piggies in a week, even though Novinha had hid the original data. If not him Miro and Ouanda would have had plenty of time to figure it out as well, just by asking questions. They would have learned a lot more about the descolada virus decades sooner as well, giving them more chance to combat it successfully.
Suggested correction: This entry first claims that it took three generations to find the solution, then states that individual in the first generation found it. If one xenologist can arrive at the solution from scratch, a literal genius like Ender can certainly rapidly come to the same conclusion using the data the next two generations compiled in the meantime.
They were all geniuses. The other 2 generations should have found out just a quickly or even quicker if they would have just simply done their jobs. It doesn't make sense.
But in Xenocide Miro's siblings like Ela, Olhado, Quarra and Grego are in the same league as Ender in intelligence, solving impossible questions without either Ender or Valentine even grasping it well enough to understand. Surely Miro isn't the only one lacking. They got that genius from their parents, the second generation xenologists Libo and Novinha who are both geniuses as well. At least the third generation should have figured it out long before Ender showed up. Mostly my point is they haven't actually done their job in all this time instead of them not being as smart as Ender to figure it out. Just ask the right questions like Ender did and voila. Its their job to ask questions but they didn't do it and their attitude towards the piggies is all wrong.
Factual error: The book mentions Bilbo's sword as being originally made as a dagger for an elf. The problem is, proportional to the wearer, that doesn't work, weapons and tools have to be made with the user's exact size always in mind. The blade or handle would be too thick, or something else would be off. I know this from trying to use a figurine sword to open envelopes.
Suggested correction: The origins of Sting are largely unknown. Even though it was made by elves doesn't mean that it was meant for elves. The book doesn't say it was a dagger for elves, just the size was comparable to one. It's only said that it was very small for Elf standards and that means it has a small handle perfect for a Hobbit hand.
Other mistake: On page 30, the book says, "Have you ever wanted to see Iris' Dragonite beside the spunky Pikachu?" despite Dragonite not appearing. This is likely because this part of the caption on this page was copied directly from the previous book.
Other mistake: On page eleven, the book says that Charmander reunited with Ash from time to time, but this did not happen as no reunions occurred during this time according to the Pokémon television series.
