One night, all the stars in sky go out.  On investigation, it is discovered that a 'bubble' has been placed around the solar system, encasing the Earth with its sun and planetary neighbours.  I can't go into too much more without giving away the plot!

This was amazing - as Egan always is.  Quantum mechanics and neural biology are the main themes.  I LOVED his ideas on eigenstates and the interconnectedness of other worlds. :)  I read this book slowly because it was so good and I wanted to make it last.
