Somebody I Used to Love by Eve Ainsworth

Lost memories. Lost loves. Can they find their way back to each other?

When Will wakes up after a car accident, he’s lost three years of memory. All he wants is his girlfriend and childhood sweetheart, Gem, beside him. Instead, nothing is as he remembers.
Gem has finally moved on from hers and Will’s break-up. With a new life and boyfriend, the last thing she expects is a call to say Will needs her – the man who nearly destroyed her.
As Will recovers, he is determined to prove to Gem that he is the man he once was. But by unlocking the secrets of his past, will he be able to piece together what caused him to change so dramatically? And, faced with the choice, will Gem continue with the safe new life she has built for herself, or will she go back to the man she used to love?
A heartbreaking and twisty will-they-won’t-they-should-they novel, perfect for fans of Dani Atkins, Jojo Moyes and NOT ALLOWED.
