Shannon Appelcline noted that the Eden Odyssey adventure series was composed of "vignette books" with short adventures beginning with Akrasia: Thief of Time, and that although a similar design had been used previously, "the Eden Odyssey adventures were some of the few to really approach the style of adventure design consistently". Kevin Wilson's Wonders Out of Time was the second vignette book released in the series, in 2001. It was followed by C. J. Carella's Secret of the Ancients in 2003.
