The Land of Taron

The first book of the YA fantasy trilogy of the Goodman children's otherworldly search for their kidnapped parents. 

It seems that nothing could be worse than waking up one morning to find their parents have disappeared and their young brother Bo bawling his eyes out, but for Jack and Brianna, the squabbling teenage sibling rivals, the worst is yet to come. 

Much to the bafflement and distress of their children, Marcus and Zelda have actually returned to their home planet, Cygnore. Marcus and Zelda, the runaway prince and princess of Bara and Rion, had a life on Earth. For 12 years, they lived happily and peacefully under the name of "Goodman". 

Bo is kidnapped. In hot-headed pursuit, Jack and Brianna plunge into a wormhole that takes them to Taron. Little did they know their impetuous arrival in Taron has placed the lives of their parents in peril. Locals catch them and bring them to an arena. In bewilderment and dismay, Jack finds himself fettered to a wall and examined by a smouldering-eyed and blue-skinned young woman of Bara, Lady Cici. 

Lady Cici, the daughter of Lord Shusha, has come to the arena for one and only reason - to have them killed. She is to be engaged to Prince Marcus, their father, and she cannot afford their existence to jeopardize Marcus' life and her forthcoming engagement. She must have them killed, and the arena, where slaves routinely fight to the death, is the perfect place.
