Ever since the old DC TNG comic (which I loved), I've been a fan of Friedman's and this novel is great.
Actually, it's my fave post-Nemesis book. I grew thoroughly sick of the heavy dependence on the Borg (Not all fans are obsessed by these cyborg bogey-men! They've been so overused), and so this one stands out as a favourite. Friedman always had such a good handle on the characters.
Was this the last Trek book he did? He needs to come back (no offence to the current crop of writers, but Friedman and Vornholt are my faves)
