The Cordovan Vault

Kayla and Quinn are having a really bad weekend. For 14-year old enemies whose normal life means that they are forced to live together because her brother married his sister, it takes something extraordinary for things to be really bad.

Like their house exploding.
Or people trying to kill them.

When a mysterious DVD turns up with the message "We are not who you think we are," they begin a crazy adventure to figure out what that means and they find that nothing is the way it seems.
