I’m avoiding finals so I made a family tree of some of the major families from @tamorapierce’s Tortall series, using A Spy’s Guide, the fan wiki, tpwords, and various other resources. 

Thank you! The POTS series is my favorite, so I don’t have nearly as many recommendations for SOTL. Some of my SOTL recommendations are in the POTS time period, but focus on Alanna. One of my previously recommended authors, devilinthedetails, also writes some SOTL works, especially about Alex. I’ll especially recommend this piece and this piece, but if you go through the Alex tag, anything written by her won’t disappoint. LadyLingua writes (exclusively?) SOTL fanfic. I recommend a couple specific pieces below, but you can also look at her page for more.
