Maybe 2.5 stars. Interesting concept but such clunky writing and dialogue that I struggled to get through it. Can't believe this book is so highly rated on here. Felt that the story simply skimmed the surface of most of the characters' interactions, probably due to the wide time range that takes place over the course of the novel. Had a lot of potential, but really fell short. Strongest writing was describing Asha's experiences in India. Weakest was any part concerning Somer. Very one-dimensional characters.
