Her Fearful Symmetry by Audrey Niffenegger

After her bestselling novel, The Time Traveler’s Wife, Audrey Niffenegger returns with a wonderfully creepy ghost story about twins and London’s High Gate Cemetery.

Elspeth Noblin dies at the beginning of this new novel, but she sticks around her apartment watching over her twin nieces from America,  Julia and Valentina and her younger lover Robert. Robert is writing his thesis on the famous London cemetery where Karl Marx, George Eliot and Christina Rossetti are buried. Elspeth leaves her money to her American nieces, who are currently aimless twenty-somethings, on the condition that they live in her apartment for a year and don’t invite their parents. Also in the apartment building is Martin, a crossword puzzle setter with crippling OCD, whose wife has to deal with his constant hand washing and rituals. There is a lot of obsession going around: Julia and Valentina with each other; Robert with his dead love Elspeth; Robert with the High Gate Cemetary and of course with his rituals, tics and hoarding.

It starts to get complicated when Robert falls for Valentina and is torn between a ghost and an innocent virgin. Fans of the macabre will be pleased to find grave robbing and hauntings.
