Borrowing Time

Barely escaping with their lives from a time one hundred years prior, Sam, Kathryn, Paul and Melissa thought that the fire stone saga was behind them until Sam received a letter from someone named Sasi, a distant relative who lived in Lampung, Indonesia. It was an invitation to visit and included round-trip airfare. There was no mention of the purpose of the visit, but upon arriving, Sam learned that the fire stone was still very much in their lives.
What does one do with something that defies logic, has magical qualities and an undiscovered set of possibilities? Sasi knows as much as anyone, but knowing that her death is near, calls on Sam to take possession of the fire stone, something he wants no part of. She urges Sam to witness what she has learned and together they discover a way to look back in time and have the opportunity to speak with Kashif, an expert in the understanding of the powers of the fire stone.
Unfortunately, Hamza, one of Sasi's students from years past, has knowledge of the fire stone and, suspecting that her death is near, has other plans. What lengths will one go to in order to possess what is not theirs? How many have to die along the way? And, if you don't understand the powers of the fire stone, is it really wise to possess it?
