Absalom's Daughters by Suzanne Feldman

Sweet as molasses, heartwarming as pecan pie and dangerous as a boy's promises on a hot summer night - two half sisters set out on an adventure to get what is rightfully theirs and end up finding friendship and maturity. Judith is white and Cassie is black and they share the same no good dead- beat father who has run out on both families in search of his golden ticket, inheritance money from the family estate in Virginia. They decide that part of that money should be theirs and they set out in a junk car and no money from Mississippi to Virginia in time for the decision over the money.
With a bit of luck , some truly kind souls along the way and a lot of moxie these two innocent girls manage to land on their feet. Wonderful heartfelt and undeniably Southern, this debut written by a Yankee author is sure to put a smile on your face.
