This is another in his Crosstime Traffic series and is set in the Agrippa Rome era. When it comes to the Crosstime books the first thing to remember is that it’s not time travel but rather travel between alternate Earths. Crosstime Traffic uses this ability to send people to the alternate Earths to trade for materials and foodstuffs that are needed in the home timeline. They also spy on the other Earths to make sure that none of them invent Crosstime which would give the home timeline competition at the very least or could bring about a war with that alternate at the worst.
Harry is in great storytelling form again and creates characters you can sympathize for and empathize with very easily. In this particular story a family is set up as merchants selling things like mirrors and such for grain when a sudden case of appendicitis hit the mother and causes the two teenage children to be left in the alternate alone. It’s only suppose to be for a few days but something goes wrong in the home timeline and the teens find themselves cutoff entirely. Now it’s up to them to make their way the best they can while waiting to see if they will ever be able to go home again. To make matters worse a war breaks out and their town is besieged.
If you like what if type stories or just a quick paced read then this one is one you’d want to try out. I’d give it a solid 3.5 out of 5 stars and hope you enjoy it as much as I did.
