I know some people might have felt less involved with Kel's story because there's no big one true love situation. There's definitely some romance, but there's no one in particular that she ends up with definitely. I actually think this might be one of the reasons I love this quartet so much. It felt a lot more like what I was like growing up: I was definitely interested in a more than a few boys, but I was never interested in taking it very far. Basically, like Alanna there are a lot of love interests - but unlike Alanna, there's not lots of sexy time. And I think it's important that both of these things are put into stories. Both that it is ok to have sexy times if you want them, as long as it is your decision, and that if you aren't ready, then you don't need to do that either. Both of these situations are good, no one option is better than the other. And I think it's great that you see heroines who really only have significant interest in one guy (Daine, Ali) or that there's serious interest in lots of guys, but the heroine gets her one guy (Alanna), or that there's interest in lots of guys, but the heroine isn't ready to settle down to have her one guy yet, so she doesn't end up with anyone (Kel). And she's happy like that.

Kel also doesn't have Alanna's temper, Daine's emotionally charged background, or Ali's quick wit, so I suppose even her personality and background doesn't stand out quite the same way theirs does. And again, I don't think this is a bad thing. A lot of things about Daine's character are really, really good - she's patient and mild-tempered (at least outwardly - she definitely fights to portray the calm people think she has) - but they are seen as sort of boring traits. The same with her background - she's from a diplomats family, and her family seems to deeply love her. She didn't hide who she was half her life (Alanna), have her family murdered (Daine), and Ali kind of makes up from having such a privileged background by being so snarky and witty (my opinion haha). Kel's personality just seems so much quieter than the others, and is more of a team player (even as she ends up being a leader) and I think who she is as a core is just so unappreciated a lot of the time. In fact, while browsing for awesome Kel fanart, I came across minuiko who is a hard core Kel fangirl, and man you should read what she wrote on why she loves Kel so much. I mean she just really nails down everything I'm trying to say here. And on that note, I'm going to leave you with one of my favourite paintings of hers (I think it's because Kel is such a giant and Daine's hair is like....flawless).
