I Liked My Life by Abby Fabiaschi
Maddy was a loving, devoted stay-at-home mother... until she committed suicide, which left her husband Brady and her teenage daughter Eve heartbroken and reeling, wondering how they can possibly continue without her. Maddy, however, isn't quite done with them. In an attempt to fulfil her family's needs, Maddy watches and meddles from beyond the grave, determined to find the perfect wife and mother to replace herself and heal her family. That's when she finds Rory: a free-spirited schoolteacher, who Maddy manoeuvres into Eve's confidences, but who turns out to be harbouring a tragedy of her own.
