The best Lost Girl Bo/Lauren fanfics in my opinion:
Ways To Tell You I'm Sorryby heartsways
This is a succubus and a human trying to have a "normal" relationship. It would already be difficult if this was a "normal" succubus and a "normal" human, but we all know that our dear Bo is a trouble magnet and our dearest lovely doctor isn't exactly free. So yeah, lots of well-written girl-on-girl drama, yay!! \o/
Lost and Foundby bellataggart
Bo is not talking to Lauren, they run into each other and are suddenly thrown into a situation. I'd like to think this is them finally getting to know each other beyond what the show showed us, you know, beying the sexy girl-on-girl doctor-patient action ;)
Who's Lauren out of the lab? What's Bo like as a girlfriend? I hope to find that out in this story.
