"Even before he got electrocuted, Jason was having a bad day."

The Lost Hero, by Rick Riordan.

"The two snake haired ladies were really starting to annoy Percy."

"The end of the world started when a pegasus landed on the hood of my car."

One of my fave first sentences is:

just thought I'd share!

"In a city called Stonetown, near a port called Stonetown Harbor, a boy named Reynie Muldoon was preparing to take an important test."

~ The Mysterious Benedict Society, by Trenton Lee Stewart 

My autocorrect hates me right now. But aside from that, I love this sentence probably for no reason other than that this book was a defining feature of my childhood (I listened to it on audiobook when I was about three years old and have read it about once a year since then.) So, obviously, the first sentence of something that means so much to me makes me feel happy and at home just reading it.

"Who are you?"

~ See You in the Cosmos, by Jack Cheng

This sentence is just so perfect. I rarely see books with a first sentence that can so perfectly tell the reader what the main character is like, and this sentence (especially combined with the next few sentences, but even just that sentence by itself) basically sums up who the main character is: a boy who wants to explore the universe and ask questions about everything he sees.

"Rain fell that night, a fine, whispering rain."

~ Inkheart, by Cornelia Funke

Just a beautiful sentence, and it describes the aesthetic of the rest of the book so well.

- "Of the first few hauntings I investigated with Lockwood & Co. I intend to say little, in part to protect the indentity of the victims, in part because of the gruesome nature of the incidents, but mainly because, in a variety of ingenious ways, we succeeded in messing them all up." (The Screaming Staircase by Jonathan Stroud)
