An adventure series mashup built on Indiana Jones-like tropes picks up steam with this second volume.
Three months have passed since eighth-grader Jake Ransom and his older sister Kady returned from the ancient land of Calypsos on Pangaea, where they saved the inhabitants—Neanderthals and lost Roman legionaries and ancient Maya—from the evil magister Kalverum Rex. Neither teen knows any more about the location of their archaeologist parents, missing three years now, but both are sure that their parents are lost somewhere in time. After an attack on their home, the siblings visit an Egyptian exhibit at the American Museum of Natural History only to be attacked again by the blood magic of Kalverum as he seeks the Key to Time. They are thrown into the desert kingdom of Deshret, cut off from the rest of Pangaea by a flesh-tearing windstorm. The bracelets given them by the elders of Calypsos also draw in their friends from their last adventure, and the five find themselves once again battling the Skull King and his minions while trying to find traces of their parents. Rollins' second Jake Ransom adventure is tighter, more magical and more thrilling than the series opener.
Likely to win Jake more fans, this will have adventure seekers of both genders clamoring for volume three (likely to deal with Norse lore, given the dropped hints). (Adventure. 9-12)
