Katherine Ramsland has crafted a one-of-a-kind book, allowing the reader to journey directly into the mind of BTK, a.k.a. Dennis Rader, a serial killer who eluded authorities for over thirty years. I could ramble on effusively about what she has accomplished through her dialogue with Rader and her review of tons of prime source material, but I won’t. Just know this: It’s a hell of a book. Buy it. Read it. It may keep you up at night, but you won’t regret it.
