Book excerpt: C-3PO, R2-D2 and BB-8 are on a special mission to the desert planet of Tatooine for the Resistance, but between befriending banthas and cheering on pod races, BB-8 and R2-D2 are having a hard time focusing. What's a droid to do but have some fun in the sun? It's a good thing everyone's favorite protocol droid is on hand to keep the mission on track. But one thing is for certain, C-3PO does not like sand!
