Thank you to Netgalley and Hodder & Stoughton for a copy of this book.

Identical twins Nan and Ana are left reeling after their mother, Elena's suicide. They want revenge on the literary critic, Eben who they deem responsible due to his constant criticism of her work.

Eben requests access to Elena's diaries in the National Library, when Nan and Ana work, in attempt to clear his name. With Eben in the library Nan and Ana start their carefully planned revenge plot; the plan, however, quickly unravels.

This is a thriller with a dystopian setting; while I enjoyed the thriller aspect, with all it's twists and turns, I found the world building lacking.
