The Professor’s Assistant free starting Friday

Steampunk adventure and m/m romance! Parallel worlds, time travel and a chase across 1885 London and Paris.
Since I put The Professor’s Assistant into the Kindle Select program for 3 months only, I though I might as well take advantage of the promotional opportunities that come with the program. I can have the book available free for five days, so it should start this Friday, April 11,  and go through Tuesday. I hope this will garner a few more reviews.  It has one excellent review, but it would be nice to see a few more reviews, good or not. I hope you will all take advantage of the opportunity!
Here is the full blurb:
Lured by rumors of a momentous invention, Agent Julian Blake steps into the New York Gate and emerges outside London.
It is the same year, 1885, but an earth parallel to his. The two timelines are almost identical, but the slight variation is enough to threaten his mission as it includes an attitude toward same-sex attraction that is less than accepting.
He never expected that difference to pose a problem. Julian has an important mission to complete–a mission with far-reaching consequences not only across the alternate earths, but into their pasts. For the momentous invention is a working time machine.
And the inventor’s assistant is a beautiful, auburn-haired young man named Daniel who causes Julian to disregard the Department rules he has lived by for so long.
But there are others interested in the professor’s new invention, and when tragedy strikes, the professor’s assistant might just be the only person left with the knowledge to recreate the device.
Now Daniel is a target, and Julian is in a race to protect him and retrieve  the knowledge of the time machine from those who would misuse it.
