Time Crystal 2 by Wyken Seagrave

The story so far: When Irish school teacher Sam Fitzpatrick and CERN scientist Michael Zhang are absorbed by a black hole, they find themselves outside the Universe on a planet populated by gigantic insect-like Entroilians and Argolaths. The Universe is merely part of their elaborate lifecycle. Michael breaks the crystal machinery surrounding it and fragments fall into the Universe where time stops everywhere except near these crystals. Sam can talk to people who hold crystal, and the insects think they can fix the machinery and restart time, so he tells his step-daughter Catriona O'Brien to collect all the fragments and bring them down the time tunnel. But handsome Hungarian entrepreneur Alex Karolyi knows that firefighter George Gabor will not allow crystals to be removed from CERN. When George tries to catch them Alex flees and Catriona tries to fly into the Time Tunnel.So begins an epic adventure that will take Catriona on a journey back through the whole history of the Universe. Time Crystal is a timeless adventure-romance including domains both great and small you have never experienced before. Few works of fiction have ever encompassed such a range of ideas and environments, such sheer imaginative scale.
