Kiss of the Raptor by David Falkayn reviews
A Romulan warbird finds itself in the ME Universe as Subcommander V'lana Avesti discovers that both universes face a common menace. Story begins at beginning of ME2 and will continue through to ME3. Events will diverge from canon-they have to in a story like this. I'm rating this story M because V'lana has a potty mouth and adult situations. Better safe than sorry.

NEL'AR'S CHOICE by Kansas Scout reviews
This is my response to the Alternate Ship of the Line challenge on Twisting the Hellmouth where it's Joyce who gets the starship, not Xander. Joyce dresses as her character from Star Trek Online.
