In Volume 7 of the Dark Horse Clone Wars series, five months before Ep3, she "died" in Obi-wans arms, he puts her on a small medical craft to "Take her to Coruscant for a proper funeral." but during transit she wakes up (Sith meditation slowed her functions), and tells the pilots to change course, "Just far away. Far from the Jedi, from this war, from Count Dooku. Just fly as far away as you can."
and I assume that is her end.
