Jack, the Giant Killers and the Bodacious Beanstalk Adventure by Frank Wood

All roads lead to the North in the second book of the Jack and the Giant Killers series. The action that began in Book One branches out in two parallel narratives as Jack and the Giant Killers break up. They must save their beloved mentor, Abel, and round up the elements that the cruel giant, Gorgo, requires to open the terrible Hateful Gate. Failure would mean victory for the ruthless thunder giant, Gorgo, and his equally horrid family, who are more determined than ever in their relentless march to absolute power in Ooom.
