When Connie gets a letter from the dad she thought was dead, she sets out to discover why he left her, eight years ago, sitting in an airport cafe with only her pet chameleon for company. Since then she lives with her foster mum, a cleaner at the airport, and lives in hope of someday seeing her dad again in the place she last saw him. With her new friend, a fearless, fossil-hunting boy called Thyo, she tracks her dad down. But as he reveals his true colours, Connie starts to wonder if she's made a very big mistake.
