Whilst this book is about a serious subject, it is amusing in places although for some it may be too close to home to be amusing. The way Elizabeth is thinking seems very structured, ultimately you realise she is an unreliable narrator and there is things she is forgetting and confusing. She is confusing her friend Elizabeth with her sister house g missing during her childhood. Her search for the woman / women she is missing shows how capable she is yet, misguided.
An enjoyable read regardless of interest in dementia.
