Timebomb - Scott K. Andrews
Mind-bomb The first of a trilogy, Scott Andrews' Timebomb has some good ideas, some strong characters and - operating as it does with time travel - it has lots of interesting places to go to in the subsequent books. The first book takes place mostly in the 17th century in the middle of the English Civil War, but the far future, the present and even some hints of events in the even more distant past, make this a highly potent mix. The strength of the concept is bound up in its central team of three characters who come from the past, the present and the future. 17 year-old Jana is from New York in the year 2141, 18 year-old Polish-born Kaz is from the present-day and 14 year-old Dora is a maid in Sweetclover Hall in Cornwall in the year 1640. Having been brought together by some sudden and not yet entirely explained phenomenon, they are able to draw on their individual talents, local knowledge and futuristic body-implant enhancements to deal with... well, that remains to be seen...
