Red harvest: star wars legends (Random House USA Inc)

Unlike other young Jedi sidelined to the Agricultural Corps--those whose abilities have not proved up to snuff--Hestizo Trace possesses one extraordinary Force talent: a gift with plants. But suddenly her quiet existence among greenhouse and garden specimens is violently destroyed by the arrival of an emissary from Darth Scabrous, a Sith Lord with a fanatical dream poised to become nightmarish reality.For the rare black orchid that Hestizo has nurtured and bonded with is the final ingredient in an ancient Sith formula--crucial to the Dark Lord's obsession, but with consequences far worse than fatal.

Now, spawned aby a heretofore unknown virus, the rotting, ravenous dead are rising, driven aby a bloodthirsty hunger for all things living--and commanded by a Sith Master who lusts for power and the ultimate prize: immortality...

no matter the cost.
