Hack started pushing the envelope in the Junior Ranger saga with this entry, which contained almost none of the outdoorsy adventure found in the early books and focused on hardcore graphic sex. Publisher John Kane was worried that it would alienate the readership so he insisted that Hack add a subplot about a butterfly collector lost in the park. Hack obliged, but had the Lepidopterologist kidnapped by a gang of roving hippie chicks and savagely raped.
