The Echoes by Evie Wyld

Max didn't believe in an afterlife. Until he died. Now, as a reluctant ghost trying to work out why he remains, he watches his girlfriend Hannah lost in grief in the flat they shared and begins to realise how much of her life was invisible to him. In the weeks and months before Max's death, Hannah is haunted by the secrets she left Australia to escape. A relationship with Max seems to offer the potential of a different story, but the past refuses to stay hidden. It finds expression in the untold stories of the people she grew up with, the details of their lives she never knew and the events that broke her family apart and led her to Max.
