Zendaya's not gonna like what happens to Chani in "Children of Dune"
I hope the little feminist Californian's up for becoming a useless concubine that's bored because she's not allowed to go into combat anymore, gets poisoned by Princess Irulan (the princess was forced to do so by the Bene Gesserits who were working to sabotage the new emperor's rule), her metabolism shoots through the roof, she gives birth to two fraternal twin children (they are Paul's) who are Awakened just like Alia, and she dies. Only time she'll come back is probably through figurative, symbolic scenes where the kids are using her personality to keep the other ones at bay inside their heads.
Don't believe me? Read the novel, the Dune Encyclopedia entry on Chani, or watch that horrible "Children of Dune" miniseries sci-fi channel made a few years ago.
