Wow! Just found this one - have been swamped at work. Of course a little wary - not all fanfic is created equal . . .
I very much enjoy the setup and too very much like Ezri Dax. I enjoyed Jadzia's character but don't think she was fleshed out well enough in retrospect. Loved Lives of Dax and find the whole concept fascinating.
Then there's Spock and it's all over. So far his characterization seems very faithful. As a a little bit of a Vulcanoidophile the Romulan element is the final hook. I very much look forward to your subsequent installations!
