Cursebusters!

Budding-psychic Reeno is the most accomplished teenage burglar in California, but one tiny screw-up and poof!she's sentenced to Bad Girl School. And that isn’t even her worst problem. Her sister Haley’s dying of an illness no one can diagnose, and now she can’t even help.

But wait, maybe she can! The school psychics have found each other and formed their own club. With the help of her gay friend Carlos and the other Ozone Rangers, Reeno finds out Haley’s disease is the result of an ancient Mayan curse. And A.B., the group's sinister non-faculty adviser, claims he knows how to break it.

All Reeno has to do is time-travel to an ancient Mayan city and steal a little item A.B. needs to save the world. Since she’s an ace thief, he has complete confidence she can execute the task before the outraged Mayans can execute her.

But can she trust A.B.? Despite his cuddly appearance, she knows he’s a merciless predator and ruthless assassin.

And he's not even human.
