The Circus Thief by Alane Adams

He tries to get his dad to give him an allowance but he won't pay him for regular chores.  However, he will take him to the circus...

Spark Press and Net Galley let me read this book for review (thank you).  It will be published November 6th.

His son gets to ride the circus horse.  He finds they plan to get rid of the circus horse, which bothers the son.  Then the horse takes off and the circus officials accuse the boy of stealing the horse.  His father saves him and the horse.  Thank goodness!
