Since I published my debut novel, Tiger Drive, in 2018, I’ve seen my share of scams. The more books I’ve published, the more calls, texts, and emails I’ve received from supposed reviewers, book clubs, television producers, and popular authors. As technology advances, the schemes become harder to spot and filter out.

But, I’m cautious by nature thanks to my upbringing (if you’d like a fictional adaptation or taste of it, read Tiger Drive), and I’ve grown into a literary citizen. I enjoy looking out for my fellow authors. So, if you receive an email from another author like the one that I received below from Colleen Hoover, check yourself and follow these simple steps before you get excited and reply or click on any links.
