The Fire in Thunder Hollow is the second book of the Thunder Hollow series. The owls have prospered under the protection of Brownie, the golden eagle. The hollow is filled with the home trees of the owls. As the good times continue, the morals of the owls begin to slip. The young are not as well taught about social behavior. They begin to create problems for themselves. Soon, the younger owls have a secret hiding place and a charismatic young leader. The young leader wants to start a new community which would be ruled by him. When the young owls' plans are discovered, they return to Thunder Hollow and settle down, all except the power-hungry young leader. Angry over his rejection, he sets fire to Thunder Hollow, destroying it. Only a few owls survive the fire by flying away. They fly so far that they cannot find their way home. Brownie, the eagle spends every summer searching for them, growing old and discouraged as the years roll by. The owls, living in a dismal swamp, are losing their memories of Thunder Hollow. Will Brownie find the owls before he dies of old age, or will the owls pay the ultimate price for their rebellious ways?
