Saleena Sanchez and the Cursed Crown

"Saleena Sanchez is a teenage witch who doesn't know any spells. She doesn’t like adventures either, so imagine her terror when she is kidnapped from the home of her protector, Michael Mason, by two evil Masters. The horsemen haul her off in a prison wagon, along with a handful of boys, to a desert mine manned by other abducted orphans. The cavalry of overlords, meanwhile, are desperate to locate a totem of theirs that's gone missing - a notorious crown whose dark magic has bound many in slavery throughout time. The feisty Saleena convinces her new mates that, with their help, she will find the crown first - and destroy it!
From afar, Michael helps his ward on her quest, using wizards to communicate with her. The young gang manage to escape the hellish mine, fleeing through strange and often whimsical landscapes, the Masters ever hot on their heels. Soon Saleena is tapping into her dormant witch skills and leadership abilities. Michael's capture, however, presents her with an unthinkable dilemma: will she have to return the cursed crown to the evil ones so that her beloved protector's life can be spared?"
