I suggest you send in a bug report to TNT. I've read similar things happening somewhere on the their weekly editorials.
...what kind of pet do you have? Grarrls and Skeiths may eat items unexpectedly.. And this happened to the newly released book from the daily dare challenge as well... So if its not because your pet is a Grarrl/Skeith, then it must be an error with ALL books at the moment. In which case, like Commy said, bug report it and wait.
