After finding a type of dilithium which can survive at higher temperatures, Tom Paris comes up with the ingenious idea of attempting to cross the transwarp threshold in an attempt to find a way to get home faster. After a bumpy start and the help of Torres and Kim, they succeed in a holodeck simulation. When it is presented to Captain Janeway, she is impressed and gives them the go ahead to try it, but traveling faster than warp 10 has never before been attempted. The first run goes very well. Tom Paris manages to cross the warp threshold which means that the shuttle craft in which he is traveling exists simultaneously everywhere, but Tom then disappears and Harry is unable to find him anywhere within five parsecs. Tom somehow manages to return to Voyager through subspace, but there are unforeseen side-effects of his transwarp travel and Tom begins to mutate. The doctor tries to treat him with a type of radiation that will prohibit cell mutation; however, this fails and Tom dies. To ... Written by Leila Reid (edited by Jeff L.)

When Janeway approves the transwarp test flight, she mentions Tom Paris joining and elite group of pilots. Orville Wright, Neil Armstrong and Zefram Cochran. They failed to mention two pilots of merit - Charles Lindbergh (the first to fly across the Atlantic Ocean) and Chuck Yeager (the first to break the Sound Barrier). See more »

Just assume it's a Tom Paris holonovel
9 January 2021 | by whatch-17931See all my reviews

It truly is astonishingly bad. But knowing that going in, it is rather surreal.

You'd think the shuttle reaching "infinite" speed would be as loony as it could get, and then Tom morphing into a Sleestak would be as loony as it could get.

But, wait, there's more!

Tom kidnapping Janeway, them turning into salamanders and having babies.

Luckily, despite the "infinite" speed thing, Voyager is able to track them down, and luckily the Doctor has a hypo spray to cure millions of years of evolution.

You'd think somebody was extremely high when they wrote this, but the production is extremely solid! The makeup on McNeill is top notch, and he acts the heck out of it.
