Eight Days of Luke
is based on Norse mythology.
It is about a boy named David who lives with unpleasant relatives. One day, he is so angry that he makes up a horrible curse which causes strange things to happen. A wall collapses and a boy named Luke? appears.
David, Luke?, Astrid, [Mr Wedding]?, Thor?, [Great-Aunt Dot]?, Great-Uncle Bernard, Cousin Ronald, [Mr Chew]?, [Mr Fry]?, [Mrs Fry]?, [Mrs Thirsk]?
LR 7/10 Like many of DWJ's best books, this one combines real life with fantasy. Lovers of the Norse myths seem to particularly enjoy the antics of Loki (Luke?)
