Frozen Time: Series One - Peter  and  Pattimari Cacciolfi
Frozen Time (Series One) by Pattimari Sheets Cacciolfi is an ingenious teen thriller come scifi action adventure. It has everything - digs in Egypt that reminded me of Raiders - ancient artefact with strange powers like Stargate - and most of all, sheer energy to enthral the reader with this book's unique premise. The characters are all believable and well fleshed out and develop as the story evolves from adventure to vigilantism to addiction with power.
Teenager Timmy finds a strange orb with a set of buttons. He keeps it from his mother and father and discovers he can stop time with a press of a button. This comes in handy when he witnesses horrific crimes, stops time an saves the victims. But with every press of a button, Timmy slowly changes from awestruck teenager to ruthless vigilante and so slides down the slippery slope into hell.
The author uses everything at her disposal to describe the orb effect the psychology and makeup, unrelenting need, unquenchable thirst for power and sadly money. I will stop time here before I open up a Pandora's Box of spoilers.
Suffice to say this thrilling scifi adventure is a must read and very highly recommended.
