They aren't walking in it, they are walking ahead of it and it is right on their heels...literally. And I'm still not really seeing this bluish glow around Percy's arm. I mean I know Riptide gives off a faint light, as Percy has used that glow as a flashlight before, but I don't see that in the cover. I also see a thin white line of color around Percy's head and shoulder, but that same white line is around Annabeth's head, but that could be because of the steam given off by the lava (you can also see some steam from the rocks just to the right of Percy's right arm). There are some light blue rocks in the background around Percy's arm, is that what you are seeing?
