What a fun little adventure!
Toph is restless now that her Metalbending Academy has become a well oiled machine. Sokka, Suki and Penga, Ho Tun, and The Dark One all try to help in their own ways. In the end, we get a little bit of unexpected wisdom from Chong (aka 'Secret Tunnel' guy) and of course a little action and adventure on the way.
The Avatar universe continues to delight in even this latest graphic novel. Kudos to the creating team once again!
