Her Fearful Symmetry (2009) by Audrey Niffenegger
After thoroughly enjoying The Time Traveler’s Wife I sought out this novel, also by Audrey Niffenegger, and was very disappointed by it. Everything is there for it to be an incredible novel: identical twins, a trans-Atlantic exchange, a cemetery full of child-ghosts, an eccentric professor with OCD, and a cougar-esque love-affair. The ending was depressing and unsatisfying: all of the fascinating side-stories petered out, and only one character had a vaguely happy ending. Read at your own risk of disappointment.
