Query: GREAT BOOK FOR BOYS AND GIRLS OF ALL AGES

"the Secret of the Howling Cave" is the fifth book in the American Adventures series based on two girls in the great depression. As usual, Hildy Corrigan and Ruby Konning are finding themselves in a lot of trouble. Hildy was framed for stealing a valuable watch that she never stole. But when the man that framed her gets himself lost in a terribly dangerous cave, will Hildy have the courage and the sensitivity to forgive and rescue him before it's too late? If you want to find out, read "The Secret of the Howling Cave"! This is one of my favorite books because it is a great story about trust and forgiveness, and I hope you'll enjoy it too.
