Irma is worried that things are not going well for her at school. She doesn't think she's smart enough to be a sorceress. However, having passed all the tests, she understands that knowledge and true wisdom are not at all the same thing. In this book, fellow sorceresses from the W.I.T.C.H. embark on a third journey through time. They must find the next piece of the Shattered Orb - the Owl Fragment. From the very beginning everything goes wrong. The friends find themselves separated, and Hay Lin ends up in a parallel world, very similar to Heatherfield. The Ghost of Time Gorgon wants to take away the hard-won Fragments from the sorceresses. Will the girls be able to save Hay Lin and find their way home?
