Corrected entry: In Chapter 3, when Skulduggery, Valkyrie and Fletcher are standing outside the cottage, Fletcher says,"We'll have to let ourselves in" and Skulduggery says "relying on teleportation is making us lazy." However, Fletcher can't teleport to anywhere that he hasn't seen. Fletcher hasn't been to the house before, so why would he suggest teleporting inside when he shouldn't be able to do this? It makes no sense.
Corrected entry: On page 440, Valkyrie's baby sister is referred to as Alison instead of Alice.
Correction: Just checked and can confirm this is wrong. It does say Alice.
Correction: He can teleport to places he can see so he could have looked in through the window and got them in, he doesn't have to have stood on that exact spot before.
