The first book in an exciting new time-travel adventure series from New York Times bestselling author Krystal Sutherland, writing with Martin Seneviratne.

Pearl, the engineering whizz, has invented a time machine, and Patrick, who knows everything about every historical period, is the perfect person to test it out with her. The one thing the twins are not interested in is their dad going on and on about the legends from their homeland, Sri Lanka. But when their time-travelling gets them noticed by secret agency T.I.M.E., the twins find themselves calling up these family legends to help them in an epic battle that could change past, present and future. Jump in for a funny, thrilling time-travel adventure - who knows what will happen when!
