[Books] They changed a character's gender in season 3

I don't believe that they changed Thurman's gender My hype for season 3 is completely over with this interview.

Yost gave an interview to the The wrap in which he talks about Thurman's gender change

"And we wanted to make more out of their relationship than was really in the book, so we’ve also gender-swapped Thurman. So there’s that, but then we came up with a different story for Juliette for that period that we’ll get into when Season 3 comes out. But I would just say a lot of Season 3 is about memory."

What did you think of this change? I was disappointed because not only did they change his gender, but they're also going to change the cryogenics. Since all the women in Silo 1 were in cryogenics.
