Thor vs. the Giants [PDF ebook] 

Odin, father of the Viking gods, shares his favourite tales of his son, Thor! With his mighty hammer Mjolnir firmly in hand, Thor sets out to show the warlike Giants why he should be feared. But Thor finds his battles with the Giants to be anything but easy. Known for his strength, bullheadedness and temper, Thor find himself under the thumb of many a giant before his adventures are over. Outnumbered and outsized, Thor is forced to use his brains as well as his brawn. Unfortunately, Thor’s adopted brother Loki, a Giant himself, has a habit of complicating everything.
