calculated to bring them out again using a short burst of warp drive. However, one Klingon ship follows the shuttlecraft, and Kirk takes the Enterprise in, dispatching the Klingon ship with one torpedo. They cannot, however, now escape and the shuttlecraft is also doomed. Picard's crew study the Preserver artifact, and when Data tries to interface with it, Thorsen's essence emerges from the artifact and takes over Data. Data takes the Enterprise into the black hole where Thorsen saw Cochrane enter it a century before. The two Enterprises, once Data's body is shut off, coordinate to take advantage of gravity waves to save both ships and tractor the shuttlecraft out. By necessity, to emerge in their own times, Kirk's Enterprise must yield the shuttlecraft's mass to Picard's, and so when Picard and the Enterprise-D emerge, they find the shuttlecraft holds Zefram Cochrane and Nancy Hedford/Companion. Both of them die, even as the ship arrives at Gamma Canaris to find the planetoid has long ago disintegrated. Before the ships got too far apart, Picard sent a short signal identifying his ship by name. Kirk writes a letter on paper to the captain of that future Enterprise, to be released after certain events have occurred. Picard is given the letter not long after the Enterprise-D is lost on Veridian III. One of the common ties is Christopher's Landing, the location on the moon Titan where Sean Jeffrey Christopher made humanity's first landing on the moon of Saturn. Cochrane returned there after his successful warp flight; Kirk writes his letter there and Picard is given that letter. Over the course of 300 years... 2061 to 2265 to 2366... the environment of Titan is progressively terraformed to one where Picard is able to stroll outdoors. The events of the story were non-canonical, and conflict with what was established about Zefram Cochrane, his first warp flight, and first contact with the Vulcans, in the 1996 film Star Trek: First Contact. Reception In 2015, John Bardinelli of Barnesandnoble.com highlighted this as among of the best Star Trek novels, he praised it for tying together the crews from both the original series and The Next Generation and said "Federation is one of the best-written, most entertaining books in the shared universe.". The book appeared on the New York Times best seller list. References External links 1994 Canadian novels Alpha Centauri in fiction Novels based on Star Trek:
