five agents (chinese philosophy)

"Gabe and his friends thought they had finally discovered a way to destroy the shadow dimension of Arcadia forever. But they were tricked--and instead of saving San Francisco, they've merged it and Arcadia into one nightmarish reality. To undo their mistake, they'll have to risk the ultimate sacrifice in a high-stakes battle that will unite all five elements . . . one last time"--Provided by publisher.

"Gabe Conway has fought a six-winged dragon, bound himself to the element of fire, and rescued one of his best friends from the twisted parallel dimension known as Arcadia. Now he has to find a way to do something even more impossible: destroy Arcadia forever--before a sinister cult unleashes its nightmare of death and destruction across San Francisco"--Provided by publisher.

"When Gabe Conway and his friends find a strange old map in his uncle's office and follow it to a crumbling secret chamber beneath San Francisco, they think they're just having one last adventure before Gabe moves away. They don't expect to end up bound to the magic of the elements, or to set off a chain of events that none of them can explain. But they're about to get more of an adventure than they bargained for. For the last century, a power-hungry cult has been plotting to merge our world with a twisted parallel realm. Gabe's bloodline holds the key to the barrier between the worlds--and now it's up to Gabe, his friends, and their new elemental powers to save San Francisco from utter destruction"--Amazon.
