There is an old adage which tells us to be wary about what we wish for; well, this is particularly true for the two brothers at the centre of this story. Greg and his younger brother Lewis find a book from the library entitled The Folklore of Time and Greg persuades Lewis to say a short rhyme that purports to give an extra day, if two people say it together. What follows is worse than they could ever imagine. Unwittingly they have woken Loki, Norse god of mischief, and they have also turned almost everyone they know, including their mother and best friends into monsters. How are they going to sort all of this out?
Aimed at the 8 to 11 year olds this is fun and weird at the same time. There are lessons to be learnt by the boys including the importance of family. The mixing of school, Scotland and Loki works well and whilst enjoying the storyline the reader is also gaining information about Norse mythology. This was a book I enjoyed and would be happy to have in a school library.
