Doctor Lovebeads: The Asphalt Warrior, Book 5 (Unabridged‪)‬

In Doctor Lovebeads, Denver taxi driver Brendan Murphy, a.k.a "Murph", ignores the little voice in the back of his head that says to stay out of the lives of his passengers. Instead, he goes undercover as a hippie - muslin, sandals, VW van and all - to rescue two girls he believes have been brainwashed by a cult leader.
