What are some good short SAT prep books?

I’m an 8th grader taking the SAT through NUMATs this June. I’d like a shorter/brief (emphasis on short!!) SAT prep/review book since this is more of a casual thing, but I want to do some light prep to see what I can get.

I do plan on checking out online guides, practice test(s) and Khan Academy, but that’s about it.

Thanks in advance!
