@acitore: Thanks for the input. In this particular case I was trying to teach my daughter some ambitious words to see how she would take to them. She seemed to still like the story. The body of the story has a few difficult words too. I tried to use words that sound complicated, but have relatively simple meanings. My idea was to tell her that just because a word is big does not mean it is scary. In that way this book is different from the rest I have written. The rest can be found at

I did not think about it sounding depressing though. i'll keep that in mind in the future. Luckily the rest of the books I have written so far happen to have cheery titles.
