This was fun! A sci-fi thriller murder mystery with time travel! A scientist who was working on a device to transport matter (like star trek beam me up Scotty transporters) accidentally creates a device that sends things (or people) back in time to a prehistoric alternate version of our Earth. It is (somewhat unbelievably) monetised by selling it to governments who use it to banish dangerous criminals and, ironically when the very scientist is accused of murder he is sent back by his own machine.
His daughter then goes on an exciting quest to prove his innocence and work out what really happened involving time travel and nifty causal time loops.
I found it well written and very satisfying to read. I loved the ending and very much hope that more books are planned – I could see how it could become a nice series.
