Welcome to Eris: an island with only one house, one inhabitant, one way out. Unreachable from the Scottish mainland for twelve hours each day.

Once home to Vanessa: A famous artist whose notoriously unfaithful husband disappeared twenty years ago.

Now home to Grace: A solitary creature of the tides, content in her own isolation.

But when a shocking discovery is made in an art gallery far away in London, a visitor comes calling.

And the secrets of Eris threaten to emerge....

A masterful novel that is as page-turning as it is unsettling, The Blue Hour recalls the sophisticated suspense of Shirley Jackson and Patricia Highsmith and cements Hawkins’s place among the very best of our most nuanced and stylish storytellers.

A searing vacation thriller set on a remote island in Thailand following two mysterious women, a charismatic group of expats, and the one murder poised to bring their paradise crashing down.

Welcome to paradise. We hope you survive your stay...

There are three rules to follow during a vacation at the famous Koh Sang Resort:

1. Leave the past behind.

When Cass sets foot on the coast of Thailand's world-famous party island, she's searching for an escape. With dark secrets following her every move, Koh Sang becomes the perfect place to hide.

1. Always be careful of who you trust.

Now, years later, Cass is a local dive instructor alongside the Permanents, a group of expats who have claimed the island as their own. The Permanents don't linger on who they were before the island, simply because, like Cass, they all have something to outrun.

1. If someone discovers who you really are, run.

But suddenly, a dive student is found dead and paradise comes crashing down. Because this isn't the first mysterious death on the island, and it won't be the last. Someone knows who Cass is and they're ready to make sure justice is finally served.
