I was about 300 pages into this and was thinking this is the best TOS book I've read in a long time. Then Lucsly hears Spock and Grey talking and he realizes history isn't what he thought it was, Lucsly meets Kirk, Dulmur and Luclsy realize Kirk does future time travel tricks because he learned from them, Luclsy's telling of the story to the rest of the DTI staff that hides what happened, all that stuff. That elevates the book even further. This was a really fun read. After just finishing WtC I was expecting a similar book with a lot of flashbacks and hard core science explained but this was more of a fun adventure and a ton of integrating TOS/TAS time travel stories. This was all great stuff. I rated this and WtC both outstanding. This was a great duology.
