Her questline is very good with multiple endings, solid voice acting (with two choices of actress even), fairly lore-friendly. M'rissi's Tails of Troubles: One of my personal favorites. In particular for female followers Anum-La and Zora Fair-Child are very good in my opinion.
Some of them are 'super' followers that have commentary for large amounts of quests and locations. Dozens of new NPCs with deep dialogue trees, new quests, and some great followers. Interesting NPCs: There's a lot more here than just female followers, but the content is fantastic, and very lore-friendly.
