YMMV / Shandril's Saga

The Woobie: Shandril Shessair. When training as a Person of Mass Destruction is the only way that gives some chance to survive... and then she eventually crosses the Despair Event Horizon in Hand of Fire and commits suicide after she is convinced that she accidentally fried her true love, Narm Tamaraith, with a spellfire blast. (Hint: She didn't, and Alustriel had to lie to keep Narm from jumping off a cliff right after her when he finally woke up.) Great way to end the story, Ed. Really.
