The Gods of Asgard, Thor, Odin and Loki have been transformed into animals and cast out by the frost giants. Odd, a neglected and lonely boy with a limp, finds the Gods in the forms of a fox, bear and eagle. He befriends them, but realizes that he does not have the wherewithal to keep feeding them.
He travels with them back to Asgard, and convinces the frost giant to return to his world, and restore Asgard to the three forlorn Gods. The frost giant gladly does so, and the Gods thank and heal Odd, sending him back to Midgard (Earth) stronger, wiser and taller. And armed with a staff.
Several of Neil Gaiman’s works, while specifically targeting children, and usually a joy for adults to read. This book is an exception; it is a little too fantastic to stomach, and the challenges faced by the protagonist are overcome fairly trivially. Not his best work, to say the least.
