You said you were a Lunar Chronicles expert...Do you know how many days Thorne and Cress spent in the desert? What about how Cinder entered the ball...was it down the stairs or through a door...? Do you know Cinder's exact age (down to the day, you can figure it out you...)? Do you know how it ends? jk on the last one, but seriously, do you know?

Thank you @Cinder1221 for all the questions, I feel like you're the only person that reads this...

I'll start with the hardest question.

Thorne and Cress were in the desert for I believe 9 days. The day they landed was the first. Then it was another 2-3 days after that that they roamed alone until Jina and the others found them. Cress then sleeps for two days and they wait another day to travel. and they make it to the town that same night. Then if I add in the fact that they sell Cress to Dr. Erland that adds another day...And then that part where there's all that comotion with Wolf and there're all reunited...The day after that is I think when they go back into space...so yeah, that one took the most thinking through. 

Cinder is exactly 16 years, 9 months, and either 9 or 10 days old at the end of Cress (the 9-10 is because I don't know how much time has passed since they kidnapped Kai (if it's after midnight it would be 10 days))

Both! Cinder first entered the ball through the door and then after a guard realized she was Kai's personal guest, she entered down the stairs.

Do I know how it ends?...Unfortunately, I do not. Though I do have some very detailed estimates that involve one of the main eight dieing :( The worst part is that it is a very likely possibility. (I'm 99.99% positive it won't end like Allegiant though...thank the stars!!!!).
