Part 2 of the great time travel trilogy by bestselling author Monika Peetz ("Die Dienstagsfrauen"). Lena finds it difficult to return to her normal life. How is she supposed to forget Dante, the boy with the different colored eyes? But soon she has far greater worries: on a school trip she discovers that she continues to be watched. The time travelers are always near her. Lena's normal life - that no longer exists. She manages to slip the chronometer, with which she can travel through time, to her friend Bobbie. A fatal mistake. A short time later, Bobbie falls headfirst into the past - and can't find her way out again. Lena breaks her promise and goes back to the invisible city, because she needs Dante's help. But her adversary was one step ahead of her - and Lena must make a momentous pact with the Time Master.
