Fleetwood Mac released an album in 1973 titled "Mystery to Me." The cover featured a cartoon baboon sampling a cake, having apparently already taken a bite out of a book.

Four months have passed since the release of "Memortality," and readers have taken their first bite (not literally, I hope) out of this, my debut novel on Pace Press. I'm happy to say the reactions have been positive: a series of 4- and 5-star Amazon reviews, along with praise from respected literary magazines such as Amazing Stories and Foreword Reviews.

Many readers don't know how to categorize it. Is it fantasy? Science fiction? Horror? A spy novel? That's because I wrote to the story, not to the genre. I've never liked labels, so when my publisher called the novel "genre-breaking," it made me smile. I'm all about breaking down artificial boundaries, even if it makes things harder for booksellers to find the proper shelf for my novel.

I wasn't even sure whether to call it YA, new adult or adult fiction. Truth is, I wanted it to be all of the above. Hey, if J.K. Rowling could impress my then-octogenarian dad with a series of books written for kids, I figured that was a pretty good role model.

But one thing did surprise me most about the readers' reaction: Some classified it as a mystery. I definitely didn't set out to write a mystery. I've even been known to remark that I didn't think I'd ever write a mystery. For one thing, it's been my impression that good mysteries are elaborate exercises, and I'm mostly a "pantser," which is to say I write by the seat of my pants.  I don't create elaborate outlines before sitting down to write a book. I start with a general concept and let the story take me wherever it wants to go.

When people say the word "mystery," I tend to thing of Ellery Queen, Agatha Christie and the like. But mystery, in the broader sense is about keeping the readers guessing; it's about sprinkling enough clues around in the plot to foreshadow a twist without giving it away. And I do love twists. If you haven't read "Memortality," it's got a great twist toward the end, if I do say so myself.

So maybe I did write a mystery, after all, even if, to quote that old album title, it wasn't a mystery to me.
