"Ada knows that the best place for star-gazing is on the island in Maine where she vacations with her grandparents. By day, she tracks osprey in the trees, paddles a kayak, and hunts for shells. But she's most in her element when the sun goes down and the stars blink to life. Will the fog this year foil her plans, or will her grandfather find a way to shine a spotlight on the vast puzzle of the universe ... until the weather turns?"--,Provided by publisher.
