The good, the bad, and the ugly: New Pompeii (New Pompeii #1) by Daniel Godfrey

Capitalising on time travel never ends well.
The good
Time travel (they transport people from the past into the present, but it's actually quite complicated and gets confusing later)
Romans (always a plus)
But no romance! (even better)
Mother of all plot twists (I did not see that coming!)
Nice...
