The Call of the Pines — Lucy Walker

A miracle of piloting had kept the plane crash from killing them -- but now they were stranded in the dense Outback jungle. Two men -- Stephen, the rancher and Alan, the pilot -- two women -- young Cherry and the elegant, spoiled Tracy -- and Peter, the baby in Cherry's charge.

It was a time and place of danger...and Cherry came to realize that the peril was as much from the explosive emotional currents among the four of them as from the jungle itself!
