Doctor Who: Code of the Krillitanes

Can eating a bag of crisps really make you clever? The company making them says so, and they appear to be right. But the Doctor is suspicious, and he's right to be. Those crafty Krillitanes are back on Earth, and everyone is at risk. "Doctor Who" has been a popular strand in the "Quick Reads" initiative, and this will be one of the last to feature David Tennant before he regenerates into Matt Smith.
