Here is my teaser from The Note by Angela Elwell Hunt (Page 6):
As the people around him fumbled to obey the flight attendants, he pulled a sheet of paper from his coat pocket and scribbled a message. Glancing out the window again, he saw the blue of the water and felt a flash of inspiration. Digging in another pocket, he produced a plastic bag, then tucked the note inside and secured the seal.

"Sorry," he said, noticing that everyone around him had already bent forward to prepare for an emergency landing. "I wanted to take care of something. I'm sure we'll be all right, so tonight I'll laugh and give this to my–"
He never finished his sentence. A spark from the fuselage ignited the fuel vapors, and Flight 848 exploded. At 6:33 p.m., pieces of the plane began to rain down into the waters of Tampa Bay.
Among the shards and debris was a note.
