Star Trek: Gateways was a miniseries of seven books published in 2001, depicting events centered around Iconian Gateways and the Gateways Crisis of 2376. The first six novels were set during each of the four then-existent television series, plus two prose-only series, Star Trek: New Frontier and Star Trek: Challenger. The seventh book (originally published in hardcover) was an anthology of novellas, each providing closure to each of the preceding novels. There was also a Star Trek: Starfleet Corps of Engineers eBook presented as an "epilogue" to the series.
