Anyone helps have a hard time getting through William's parts in Echo?

I am having the hardest time getting through this book. It's such a slog. I started in mid-november and I'm only on page 206 (for comparison, I read the first book in 16 days).

I'm mainly having problems with Williams parts. They just feel so irrelevant and the subject matter is super boring. I'm at the point where I just want to skip his sections. How relevant is this side plot? I've I've seen the show so I know the relevant plot points based on that, but am I going to miss anything super important if I just skip his parts?

*I realized I messed up the title and can't edit it . It should say anyone else instead of anyone helps
