Recced because: After the Doctor leaves UNIT, several of his former companions and colleagues investigate a mysterious alien. I'm not usually someone who likes reading longer fics, and especially chaptered works (especially when those chaptered works are abandoned without a conclusion). I remember seeing this years back on who_daily and falling in love with it after the fic was completed. I find the mystery in this fic compelling. I couldn't stop reading this one, and I'm glad I did!
