Working my way through post-nemesis trek-lit (I'm a few years behind the times), but I keep finding events on Tezwa mentioned, and all that stuff, so I decided when I'm done I'm going to back-track....so I just downloaded all nine "A Time To..." books on my kindle.
All you really need to read are the last three. They deal with Tezwa and it's aftermath. I had actually read A Time for War, A Time for Peace
(the very last one in the series) and it covers the broad strokes of Tezwa.
