Null Vector is a fast and fun sci-fi read, with mystery, suspense, easy world-building, believable tech, and lots of great humor.
I'm not always a fan of a fair helping of humor in books, but in this one, it suited and made the book an even faster read.
Joe Ballen has always been a character I like, but in this book, he's particularly sympathetic due to the issues he's facing, which the author does a great job of dealing with head-on. These are not problems exclusive to the genre; they're common problems faced today, like poverty and disability. It isn't often you have an MC who's living off meager government disability funds, so I found that particularly of interest. Joe's disability isn't romanticized or tamped down for reader comfort either, which is something that drives me crazy in other books. This was handled very well and much more realistically, along with the self-doubt and insecurities that go hand-in-hand.
There's also a great noir feel that I enjoyed, being that I love film noir. If you're also a fan, you'll recognize it. It adds another layer of enjoyment to the book and atmosphere overall.
You don't have to have read the other books in the Joe Ballen series before diving into this prequel; you'll understand everything without them. This may even be the best place to start the series! It sets up Joe's character and past as well as Dollie's character beautifully.
I highly recommend this book!
