Lily leads the way
(Book)

"Lily the sailboat is small but sturdy, in a harbor full of enormous cargo ships, speedy fishing vessels, and bossy tugboats that all have somewhere to go. And something to say—mostly, 'Out of my way, Lily!' But Lily has somewhere to go, too. Out on the lake, the tall ships are coming! To leave the harbor, Lily has to wait for the lift bridge to rise. When the other ships blow their horns, 'OOHHH-pen, OOHHH-pen,' the bridge lifts up for them. But not for Lily. When she finally scoots under the bridge, the grand old ships are silently sailing toward the lowered bridge. Silently! How will the bridge know to open? Can Lily save the day?" --book jacket
