In a Dark, Dark Wood by Ruth Ware
Nora Shaw lives an isolated life, and prefers it that way. She keeps to her schedule in her tiny studio in London, and relishes in the safety that her lack of social contact provides. Then one day, an email arrives, inviting her to her school friend Clare’s hen party. Nora hasn’t seen Clare in a decade, not since she walked out of school and never looked back. Reluctantly dragged into the party, Nora finds that not everything is as it seems. Something is deeply wrong at this party, and Nora must figure out what is going on before it costs her her life.
This is Ruth Ware’s debut novel, and it is an edge of the seat mystery/thriller. Ware paints a scary portrait of revenge and obsession, but as a reader, you’re never really sure who is truly obsessed. Nora herself seems to become more and more unreliable as a narrator as the story goes on, bringing everything that came before into question. The twists are numerous and surprising, once you’re sure you know where the book is going, it throws you in a different direction entirely. The false leads and narrative dead ends keep you guessing throughout the book.
