My first thought on this book is what a unique premise it had! It's basically about time travel into the past (called a timesplash), changing something there, and then enjoying the chaos that occurs when history works to right itself. While this was first done in small jumps with limited chaos, it was basically one big party. But when Sniper, one of the bricks (that's what they call the actual time traveler), goes back further and further, creating more and more chaos, it changes from a party to terrorist activity. Whole cities are leveled, and Sniper's next splash is going to go back further than anyone ever has before, and will cause even more damage when he returns. Enough to level London, in fact. Everyone is working furiously to find Sniper before he can make the jump, including Sandra (Sniper's ex who was emotionally scarred from what happened during one of their splashes), and Jay, a cop whose friend was killed during the chaos left after one of Sniper's splashes. What ensues is a race against the clock to locate and stop Sniper before a whole lot of people die.

This was a unique and interesting story, well written and action packed. I enjoyed it very much.

4/5 stars.
