The Homemade God by Rachel Joyce

Family is everything, even when it falls apart.

There is a heatwave across Europe.

Goose and his three sisters gather at the family's house by Lake Orta in Piedmont, Italy. Their father, a famous artist, has recently remarried a much younger woman and decamped to Italy to finish his masterpiece. Now he is dead and there is no sign of a painting.

Although the siblings have always been close, as they search for answers over that summer, the things they learn - about themselves, their father and their new stepmother - will drive them apart before they can come to any kind of understanding of what their father's legacy truly is.

Extraordinarily compelling, at heart this is a novel about sibling relationships and those hairline cracks that can appear within a family: what happens when they splinter, and what it would take to mend them.
