Seekers of the Fox by Kevin Sands

 In this second installment of the "Thieves of Shadow" series Callan is the only one that sees the Chaos magic growing within his friend, Lachlan.  He knows that if he doesn't heal his friend, the Chaos will eventually take over and cheerful, child like Lachlan will turn into something much darker and more powerful. The only way he knows to help his friend is to seek the Dragon's Teeth, another magical artifact.  With the help of his new team, Callan goes to the depths, literally, to unravel a millennium-old secret and face their most powerful opponents yet.

I enjoyed the first in this series so much I put the next on hold right away.  This one was also a fun read.  I can tell the writer had a great time imagining the different exotic settings. As in the first book, the magic system is a little weak,  and the reader can't help but ask themself if five kids could really solve a mystery that had been unsolvable for 1000 years in just two days?  The warm comradery between the main characters makes up for the other shortcomings and I will look forward to reading more in the series.
