Book Synopsis

The brand new romance from New York Times bestselling author Susan Mallery

No one knows you better…

Finley McGowan lives her life by ‘rules’. Rules give her stability and stop her being hurt, something she needs more than ever after her sister’s betrayal years before.

Sloane McGowan spent her childhood trying to be the perfect daughter and sister. But when one traumatic event derailed her life, she found it spiralling out of control, until the fateful day she betrayed the one person she loves most – her sister.

When Sloane reappears in Finley’s life wanting to make amends, Finley must decide what is more important – rules or family? And, if the past is worth letting go, in order to embrace a future.

‘Unputdownable! It’s been a long time since I was compelled to stay up into the early hours of the morning to finish a book, but wow, it just had to be done! This is the first book I have read by this author but it certainly won’t be the last.’ 5 stars

‘Highly, highly recommend this book and I need to find more of Susan's Christmas books to read!’ 5 stars

‘She’s done it again! Another fantastic read! I love how Susan’s books are all so different, such individual ideas in each one.’ 5 stars

The Christmas Wedding Guest is a delight. It's so good that I didn't want it to finish and rationed chapters to make it last longer.’ 5 stars

‘Grab a blanket and a hot chocolate and snuggle down for the most delightful Christmas romantic comedy. So uplifting and loads of feel good moments it’s like having a hug in a book.’ 5 stars

‘The characters are wonderful, the town is great. I laughed, I cried and I am so glad there will be more to come. I love the multiple HEA's.’ 5 stars
