Hilarious adventure, mythical creatures and non-stop action. Two brothers recite an ancient rhyme and conjure up an extra day of the week but they had no idea it would work - or that the day would belong to the banished Norse god, Loki, master of mischief, monsters and mayhem. As the day wears on, time seems to be lagging behind. Will this day of madness never end? Can two ordinary boys outwit an ancient lord and his monstrous minions, AND get their mum back?
'At that moment the kitchen door opened and something colossal came stomping out. It was about seven feet tall with green skin and tufts of black fur on the back of its ham-like hands. A long, thick tail was dragging heavily across the floor behind it. It was wearing Mum's green summer dress and white apron.'
Lewis and Greg have accidentally turned their mum into a troll, and the town of St Andrews into a fantasy world overrun by yetis, elves, dragons and valkyries - few of them friendly.
