At twenty-two years old, Summer met Rory. Charismatic, confident, and an amazing storyteller, he was the love of her life, and they did everything together, from book festivals to escape rooms, coastal walks to paintballing. And he was always in the front row of the audience when Summer gave talks campaigning for Asexuality to be recognized under the Equality Act, supporting her to no end.

But three years later, on their honeymoon, Summer and Rory got separated during an earthquake. Summer spent a whole year in Indonesia, looking for her husband-but to no avail. He was pronounced as 'presumed dead' and eventually, she was persuaded to return to the UK without him to try and live her life.

But Summer never gave up hope of being reunited with Rory. Releasing her trauma through the pen, she wrote a bestselling novel about love and loss, reimagining her life with Rory in a world where the Earthquake never happened. A world where they had everything, a world where they both won literary awards, and a world where they overcame their IVF struggles and became parents.

Yet one morning changes everything. Summer, now twenty-nine, learns that Rory really has been found-and he's alive. He has severe memory loss, and for the last few years he's been living as a man called Robert, but Summer is sure their connection is still there. After all, it has to be, right? He's her soul mate. The two of them can take every challenge life throws at them. And she's not going to throw this chance away.

But then Summer finds out Rory is now married to someone else and has a family of his own that doesn't include her. This man insists he's not her one true love, has no recollection of her, and Summer's faced with the most difficult decision of life: reclaim her man and find a way to make him remember her and their life together or let him go so he can live happily with his new wife and children.
