Okay, granted it happening at the beginning of the series by itself doesn't mean that it is automatically lighthearted... BUT Hiro Mashima himself said in interviews that with Fairy Tail he wanted to create something light-hearted.

What you propose is fucked up to the point where it would seem out of place in such series as Re:Zero or Grimgar a Fantasy of Ash and those series deal with pretty darn depressing stuff.

To have your dead father give you hope with the title and then crush you into the dirt with the actual words of the book is something way darker than anything in Rave Master short of the two torture scenes, so yeah it would be waaaaaaayy out of place in Fairy Tail.

Also Lucy knew quite well how Kemu Zaleon's mind worked from being an extreme fangirl and she knew what Kaby told her about Kemu being a good father, so there was absolutely no reason at all for Lucy to suspect Kemu writing such a fucked up travesty you suggested.
