Two heads are better than one...
With nothing less than the future of humanity at stake, it's up to Edgar and Ellen to thwart Stephanie Knightleigh's dastardly scheme to raid all the world's balm springs -- even if it means separating for the first time in their lives. Edgar's pursuit of the Midway Irregulars leads him to the forests of Cougar Falls and an unlikely partnership with an eccentric professional monster hunter, while Ellen and Pet find themselves in the decidedly inhospitable town of Lach Lufless.
But can Edgar survive without Ellen's quick wits? Can Ellen survive without Edgar's satchel of tricks? And can either of them survive when their most important allies have become deadly enemies?
