Plot hole: Any invisible man would be blind. This is because if your retina in the eye is as transparent as an invisible man's, any image that can form on it will pass right thorough it without generating any vision signal via optic nerve. Thus your brain gets no visual signal if you are invisible.
Continuity mistake: About two thirds of the way through Ch. 1, Sookie serves a pitcher of beer to her brother Jason's boss, Shirley Hunter. But in the previous book, Dead to the World, Jason's boss Shirley's last name was Hennessey (Ch. 3).
Factual error: When the Australian astronaut is describing the Battle of Dehli, he says "Just like the limeys used to do in the colonial days." Limeys is just an American term. In Australia, Englishmen are referred to as pommies.
Other mistake: E-mails between Salander and Blomvkist on pages 311 and 312 (2009 MacLehose Press hardback) are repeated word for word on pages 370, 371.
Other mistake: On page 180, Virbank Gym is misspelt as "Verbank Gym." Also, in the section discussing the first round of the match there, the Pokémon in it are Koffing and Boldore, but a picture of Krokorok is shown.
Factual error: Britons will be grateful to know that it would be impossible for the UN to order the nuclear destruction of Great Britain. The UK, being a member of the Permanent Security Council has the power to veto any UN decision.
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.
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.
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.
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: 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: In Chapter 14, Cato is being awarded a grass crown for saving his centurion and the standard of his company. The grass crown was only given to generals or other higher officers, for rescuing an entire legion or army, and it had to be acclaimed by the entire legion he rescued. As an optio, Cato would be ineligible for a grass crown, his actions would not qualify for it, and he is said to be unpopular with his company, so a unanimous vote is highly unlikely.
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.
Continuity mistake: When the Kingdom Keepers are inside the It's A Small World attraction, and the puppets come to life, the book states that a doll locked onto Finn's arm, chomping down hard enough to draw blood. However, at the girl scout car wash, Finn shows Amanda his bite marks by lifting up the leg on his shorts.
Other mistake: In the hardcover edition, published 2008. The mistake is on page 100 - "And when did faux mitzvah enter everyone's vocabulary accept mine?". 'Accept' should obviously be 'except.'
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: 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: After the "adventure in acceleration" at Adrian, the Hail Mary is effectively upside down (Ch. 20). Then Grace gets "sick of living in the Poseidon Adventure" and rights it-meaning the storage area is at the bottom again. He goes in there to fix a leak, then "climb[s] back down and wince[s] the whole time." He should be climbing up or out, not down. Also, in Ch. 22, when Grace is in there again (finding Taumoeba poo), "Rocky calls out from below"-but Rocky should be above him, not below.
Continuity mistake: In the second chapter it states specifically that Lillith is texting on her iphone however after receiving a text from a friend she says she closes her phone or snaps her phone shut suggesting that she is using a flip phone.
