I like this novel better than the Canon "First Contact". At the same time, I like how they used the Guardian of Forever to tell a different story of the Federation that supposedly happened in another universe.

It ended well, and made this book timeless because it happened elsewhere, not on the Primeverse. Then again, in-lore, which one is the Primeverse?

Gave it 5 stars out of 5. I truly enjoyed it.
