With three prequels, it can be hard to decide where to start the Spy Another Day series. I like to think think you can jump into the series with the first prequel novella Spy Noon (available exclusively on my mailing list), with the prequel novel Spy by Night (listed as #1 on Amazon), or with I, Spy, the original starting point for me and the series (now listed as #2 in the series).
If you’re the kind of reader who HATES spoilers and/or loves to read complete series, start with Spy Noon. If you’re the kind of reader who loves to get a little more insight into the characters you already know and love (even though you already know how the story might end), you can jump in with either Spy by Night or I, Spy.
The prequels, especially the novellas available exclusively on my mailing list, were written to show some fun backstory. Spy Noon covers when Talia meets her coworker Elliott (who figures heavily in I, Spy), and Mr. Nice Spy covers an event that happens fairly early on in Spy by Night, but MNS is from Elliott’s POV.
