One cold, gray, winter day, Miss Winkle leads Katie Woo and the rest of her class on an imaginary journey, challenging them to find ways to complete their lessons on a sunny island, under the sea, or on the moon
When a snowstorm causes the power to go out Katie and her parents think their Thanksgiving dinner with JoJo and Pedro is ruined, but by being a good neighbor, Katie saves the day.
Katie's school assignment is to pick a topic and write a research paper on it, and when she picks butterflies as her subject she learns that even small animals can be very interesting.
Pedro forms a new club with his friends dedicated to solving mysteries--and the first two assignments are finding his mother's locket, and his father's cell phone.
