Win one of five RHS memberships with Three Summers!

Three Summers is the sensational new novel from Sunday Times bestselling author, Karen Swan. Set in 1950s Italy, over the course of three summers, it follows Raf, Cosimo and Fon, friends since childhood, as they become entangled in an explosive love triangle. Epic, evocative and escapist, it's a tale of love found, love lost and love denied – and is the perfect gift for Mother's Day.
