The Life Impossible by Matt HaigRead about the other entries on the list.
Matt Haig’s most recent novel is what one may call a “feel good” philosophical work, but don’t let that categorization fool you; it is far from the dull theory taught in Philosophy 101. Much like his New York Times Bestseller, The Midnight Library, Haig interweaves philosophical quandaries throughout the book, but this time, it’s an active contemplation on grief. The narrative follows a middle aged woman named Christina who’s recently been widowed and has long been burdened by guilt after the death of her child. She tries to avoid grief around every corner, until a friend mysteriously dies and leaves Christina her house in her will.
The healing process isn’t linear, an idea that Haig fully dissects within the novel. While the beginning of The Life Impossible can neatly be defined as literary fiction, there is a drastic shift in tone and genre near the midway point, when the cause of the friend’s death begins to pose imminent danger to the island. By turning grief and loss into something magical and surreal, Haig creates an environment in which we can find purpose in our pain and make sense of the senseless.
The Life Impossible is among Anna Montague's seven top novels featuring protagonists over 70.
