Okay, I stand corrected. And since Seven of Nine is my favorite Voyager character, I'm happy to see her in a novel. I actually do enjoy crossovers - I never noticed a lot of the ones in Ishmael, but I think my reasons for being annoyed at the Doctor Who references are reasonable. I just don't like Abrams' version of Star Trek and would prefer that it stay by itself. A good crossover can be quite a challenge - I discovered that a couple of years ago when I did my NaNoWriMo entry. My crossover was the Sliders TV series and Margaret Atwood's novel The Handmaid's Tale.
