Dreamer Easy

You might try "Parable of the Sower." Dawn is the first book of an iconic series, so it is good to return to eventually, but I can see how a reader would get lost. There is A LOT of sudden world building. I think this mirrors the disorientation of the protagonist. The stuff that happened between her last earthly memory and her waking up among the Ooloi is a lot to process, and I think she doesn't quite grasp it all at once. "Parable of the Sower" starts in a world that is not at all hard to see from where we are now.
