Odd meant the tip of a blade, and it was a lucky name.A short YA book by Neil Gaiman, in which the young boy hero with a disability saves the Æsir from the frost giants. Very nice illustrations by Mark Buckingham (I thought I spotted the resemblance to Fables. The story is lucidly told, and perhaps a bit of a homage to Diana Wynne Jones' lovely Eight Days of Luke which has a similar theme (though Eight Days of Luke is set in the 1970s rather than medieval Norway).
Odd's mother was kidnapped from Scotland as a girl by his father, and the frost giants get to enjoy Freya's hospitality in unspecified ways while they are occupying Asgard (though they are too big to do more than look at her, I guess). I find this rather skeevy.
