Pack Animals — Peter Anghelides

The seventh novel in the bestselling Torchwood range from BBC Books. Shopping for wedding gifts with your fiance is enjoyable, unless like Gwen you witness a Weevil massacre in the shopping centre. A trip to the zoo is a great day out, until a date goes tragically wrong and Ianto is badly injured by stolen alien tech. And Halloween is a day of fun and frights, before unspeakable monsters invade the streets of Cardiff and it's no longer a trick or a treat for the terrified population. Torchwood can control small groups of scavengers, but now someone has given large numbers of predators a season ticket to Earth!
