So, you're probably wondering why I think that Sokeefe is doomed. I read all of the KotLC books, and found a lot of clues as to who Sophie's dad is, and I've pieced together who he is. IF you want too try and see what I found, go read book one, three, eight, and nine point five. (I found a lot of clues in book eight) Anyway, if you want to know the name of Sophie's dad, scroll to the bottom, but if you don't want to know, or haven't read all of the books yet, I'd advise that you go read at least book eight before you see whose name is at the bottom of this scrolly thing. WARNING: POSSIBLY SOME SPOILERS AHEAD Sophie's biological father is Lord Cassius. This is why, I'll name two main points of why I think so. 1. In book eight, Keefe's trying to find out who Sophie's dad is, and says something like this, "Your dad can't be my dad, he'd be bragging all the time that he was the father of the Moonlark." That can be interpreted as foreshadowing. And later, Keefe says that his dad talked about Sophie a lot with Lady Gisela. 2. In book nine point five, Lord Cassius gives Keefe a passport that has Keefe's last name changed to Foster. Keefe thinks it means that his dad knows he likes Sophie, but Cassius doesn't say yes or no. And guess who shares a last name? Basically almost every set of siblings in existence.
