Curious Incident is one of my all-time favourites; I’ve read it many times. My most recent re-read was because I had booked a ticket to the West End musical adaption (also incredible and highly recommended).
The book follows the story of Christopher, a boy who is a little different from the mainstream but incredibly smart. He finds his neighbour’s dog, dead, in his own garden and tasks himself with finding its killer. Along the way, Christopher finds out about relationships, familial love and a few more of life’s mysteries.
