Tear Jerker: A Dirty Job
Also, by Christopher Moore, A Dirty Job, while hilarious, has the most touching "goodbye" scene between Charlie and his daughter, Sophie, as he dies from wounds suffered in the final battle with the Morrigan after realizing that he is not the new incarnation of Death; Sophie is. One sentence from Sophie is the worst: "Goodbye, Daddy." I couldn't stop crying for two hours. The author is a GENIUS!
