I'm so excited

Reading the book now (because of the movie announcement) and I'm very excited as well! I assume it will pick up soon before God's Promise, likely not going into her childhood years. It's a lot to fit into a movie, so unless they do flashbacks I don't see how they could make it fit. Coley is obviously a huge part of Cameron's story, so I'm sure she'll play a major part.

The casting of Lindsey is definitely not who I would expect.

I bought the book after seen the film and damn they left out like 60% of it mostly to do with Cameron pre God Promise stuff that the film only deals with. Like her having relationships with other young teenage girls, her parents dying, her Aunt plays a way bigger part as does Coley (played in the film by Quinn Shepard). You'd be shocked if you read the book to see how much the film left out.

I definitely think you could make a really strong 8 part mini series on the book and it would feel totally different to the film. I think the film is really good but after reading the book you definitely feel it was a missed opportunity. You could have tacked on another 45 minutes dealing with Cameron's life leading up to God Promise and I think it would have made the film a lot stronger.
