I liked how Graham Storrs worked out the mechanics and physics of time travel in this novel. He nicely resolved the implications of messing with the past.

Set in Europe of 2050, the world of TimeSplash is mostly familiar but with subtle twists. Everyone's got a "compatch," which seems to be what cell phones have evolved into. Terrorists use time travel as a destructive tool, funded by unnamed deep pockets (possibly the government of the United States, which has been taken over by religious zealots).

I wasn't as much a fan of the cartoonish characters. For some reason, the misogynist Sniper could have been the deranged twin of Zaphod Beeblebrox (from The Hitchhiker's Guide to the Galaxy</i); perhaps it was his evil laugh? Then there was Sandra (also known as "Patty" as in Hearst--now who in 2050 is going to want to name themselves after her??), who escapes a mental institution, becomes a brilliant marksman and martial arts fighter, and--oh yeah--she's a gorgeous 19-year-old, too.

Overall, a fun read for the plot and less so for the characters.
