First, there's John Byrne's Romulans: Schism, picking up some story threads from previous Star Trek comics by Byrne. The Klingon-Romulan Alliance continues, with all its back-stabbing and subterfuge, and Byrne even manages to work the ever-anonymous Number One into the action (she's a Commodore now).
Spock Reflections, written by Scott and David Tipton, is a great flashbacky trip through the highs and lows of Spock's life, with a lot of well-realized moments. Trekkies will appreciate the nuances, though those with only a casual familiarity with Spock's long Trek history might find the story a bit slow. The art, by David Messina, Federica Manfredi, Arianna Florean, and Ilaria Traversi, is also quite good.
Finally, Star Trek: Nero tries to flesh out the motivations of Trek's latest space loon. I thought Eric Bana's character in Star Trek was badly underwritten, and Star Trek's writers, Roberto Orci and Alex Kurtzman, weren't able to get all the stuff into the movie which perhaps they should have. They do get story credit on the Nero script by Mike Johnson and Tim Jones, which explains where Nero comes from a little more convincingly. More solid art by David Messina, with coloring by Giovanna Niro (no relation).
On an unrelated note, check out my review of Wii Fit Plus – just picked it up the other day, and it's lots of fun.
