Time Travel discussion

I am the author of a time travel novel and have just joined this group. I've listed my book as a first step.
In 'Chronoscape' the protagonist, Martin Riley, discovers how to send information back through time, but not people or objects. I mention the science behind the discovery only briefly. I admired the way Claire North didn't offer any technical explanation in her excellent novel 'The First Fifteen Lives of Harry August'. I use real world events as the plot moves from the 1990's into the future, and US and UK Governments change world events. One of the events that was changed led to my spin-off novel 'The Muslim Prince'.
I hope that's enough of an introduction.
