TOS or AOS crossover with the Sentinel

[aislinamara.livejournal.com]

 Hello all!!!

I am looking for any and all crossovers of TOS and AOS with the Sentinel series, preferably with Kirk or Spock as a Sentinel or Guide.  I have read the stories by Keira Marcos. I don't care about pairings, but I am partial to Kirk/McCoy and Kirk/Spock. That said, I will take what I can get.  Het, gen, slash are all fine with me. Complete fic only, please!  Self-recs are welcome.
