Depth Charge

Allen Strange is excited about tagging along with Robbie and Josh on a day trip to San Diego. Even the ride down is amazing -- they don't have trains back on Xela, Allen's home planet. But while they're sight-seeing, Allen senses some weird energy waves, almost like a Xelan Comm signal. Have some of Allen's friends come to take him home?Allen and Josh soon find the signal's source, and discover it's linked to a shipment of torpedoes that sank in the San Diego Bay during World War II -- torpedoes that are now active!Time is running out, but Allen can't diffuse the torpedoes without absorbing their energy himself. And not even a Xelan can contain that much power without risking his life.So which will it be? The end of a major metropolis?Or the end of Allen?
