Trilby Moffat is in grave danger, again. When she arrives on a secret island outside of time, in search of her missing mother, she knows she's in trouble. A strange festival is about to take place and Trilby is the guest of honour. Travellers from all over time are flocking to this mysterious carnival with its treasure markets, floating cupcakes and a terrifying surprise. Now Trilby and her friends must race against time (literally) to reveal the dark truth lurking beneath their beautiful island. Friendship will be tested. Loyalty is stretched to the limits and a skittish prehistoric bird named Anton will destroy Trilby's favourite jumper. Just when she thinks time is on her side, Trilby is about to get a perilous promotion.
