Aah, I'm late!! XD, I don't actually ship myself with Thorne (I have a gf in real life) but I definitely ship the characters Cress and Thorne!! Glad you enjoyed it.
I loved Stars Above!! I actually read it before finishing Winter, then reread it afterwards. The last story was beautiful - especially because the end of Winter was kind of abrupt and didn't resolve everything.
Jacin and Winter are adorable, Kaider are my OTP, and everything is so well-written and plotted and developed and it may be my favorite series of all time. Overall, glad you loved it. :)
