Twelve year old Chase Masters and his father follow natural disasters and are currently in Mexico where the Rossi Brothers’ Circus went missing after a massive earthquake.  Separated from her family, Nicole Rossi is anxious to find them and check on the animals.  Chase, Nicole, and a few remaining circus members form a team to locate and provide assistance.  A volcanic eruption is imminent, a tiger is loose, thieves intercept them, roads are blocked, equipment fails, and the air is filling with ash.  Much action fills this third book of the Storm Runners series.  Although this is the final book in this adventure, one does not have to have read the previous books in order to get caught up in the fast-paced action.  This series will most certainly attract reluctant readers.
