Star Trek: Enterprise
I wrote these two stories long before I came up with the idea for the Osiris. They are not as good but I thought I would include them here anyway as I wrote them. Feel free to read them and email me if you have any queries on any points of accuracy.
Event Horizon is first, set within the series.
Silent Allies is set after the chartering of the Federation and at the moment does not have anything to do with the current Star Trek timeline as seen in "These are the Voyages" (last episode of Enterprise season 4)
Star Trek: Vanguard
This is another Star Trek story I wrote and the first to feature a female captain. I suppose you could say that it is a precursor to the Osiris stories.
It is called Revelations and is set during the Dominion War.
