"Life has settled back to normal in the old house. Becky and her mom are getting used to having Billy around, as he performs various household chores, utilizing his amazing strength. Nothing could be better, aside from a jumpy relationship with the cat. Until one day Billy hears screeching in the back yard and runs out to find a very large owl attacking his housemate. 'I hate that cat, but it's OUR CAT!' yells Billy, and chases the owl off. Billy soon discovers that the owl he has just scared off has left an egg in his nest. When the egg hatches, it's up to Billy to reunite the baby owl with his mother, and the two head off into the deep, deep woods in search of her" -- from publisher's web site.
