RIP, Janet.
While researching Janet Kagan's SF backlist recently, I found a reference to a supposedly hard-to-locate 1998 revised trade paperback edition of her SF novel, "Hellspark" (1987), and a brief mention that it contained new Afterwords by Janet for both "Hellspark" and "Star Trek: Uhura's Song".
Thanks to Amazon's links to the second hand market, I located superb-condition copies of "Mirabile" (Tor hardcover, 1991) and the revised "Hellspark" (MeishaMerlin, 1998). They arrived last week - and yes, the Afterword to "Uhura's Song" is so cool - five new pages of classic Janet talking Star Trek!
