While volunteering at the Summer X Games in San Diego, Wall and Kevin become involved in mysterious happenings just as the sports competition heats up.
i thought this was a pretty good book the time that they had the caracters climbing the walls or when they were competing was awesome but the mystery was easy to figure out this is probably my forth favorite of the 8 book series i think the to best are deep powder, deep trouble the first one in the series and total whiteout the last one in the series but this is good book but i would recomend buying the whole series it give i a good feal for meeting the main caracters but all in all this is a good book
