Is This a Great First Line or What?

Friday night after the matriculation ceremony at my school, I met my husband and daughter at a restaurant for dinner. The whole time, my daughter hardly said two words because she had her nose buried in a book, which turned out to be A Drowned Maiden's Hair by Laura Amy Schlitz. She finished it today and was raving about it, and since I was between books, I asked if she could keep it out of the school library long enough for me to read it too.

I started it tonight, and I was hooked from the first line.

On the morning of the best day of her life, Maud Flynn was locked in the outhouse, singing "The Battle Hymn of the Republic."

What masterful technique! This sentence foreshadows what's going to happen, hints at backstory, introduces the protagonist, and gives us an idea of her personality. Plus, it makes me so curious I must read on.

Ah, but therein lies the problem! This is really not a good time for a book that grabs me by the imagination and won't let go......I should be writing syllabi......
