Her Fearful Symmetry - Audrey Niffenegger

This ghostly tale of secrets and contested identities is gripping and enjoyable, and the parts that deal with the claustrophobic and complex nature of life as a twin are compelling and believable. Some of the characterisation was a bit heavy-handed though, and several key moments in the plot didn't quite ring true, so overall I agreed with the friend who lent it to me that the effort involved in suspending disbelief was too much at times, and this book doesn't manage the difficult challenge of living up to the expectations set by The Time Traveller's Wife.
