This chapter book is much more sparse in style than the usual fare from Neil Gaiman. Absent is the expected meticulous development and overall cleverness that make his other works such a delight to read. It is for younger kids so maybe he didn't feel the need to work out the story and character the way he usually does.
"Odd and the Frost Giants" is a simple tale about an unlucky boy back in the days of the Vikings who comes to the aid of Odin, Thor, and Loki as they try to take back Asgard from a crafty Frost Giant.
Considering Gaiman's superb writing skill, I think he should have taken what is really a sketchy short story and developed it into a full middle grade novel with a satisfying plot and main character arc. As the narrative raced past plot points at breakneck speed I found myself wishing he had taken the time to do just that.
In short, while "Odd" is better than many titles in this niche, I just didn't get my Neil Gaiman fix off this one.
