Hum yeah I knew about those ones... But I'm more interested in the original novels! Aren't there any involving Kirk, Spock and Cie?
You might want to check out the novels based on the "Enterprise" TV series, since Enterprise takes place before the two universes split. Personally I find that "Enterprise" works better with the 2009 and 2013 movies than it does with "Star Trek" (1960's series), The Animated Series, The Next Generation, Deep Space Nine and Voyager.
