In this deliciously twisted thriller about a deeply dysfunctional marriage, a feuding couple’s romantic getaway turns into a deadly game as they both plot each other’s murder.

Once driven by an all-consuming passion, Declan and Cressida’s marriage has fallen by the wayside in a series of infidelities and unsuccessful fertility treatments. The neurosurgeon and the therapist seem able to fix everyone’s problems but their own. After so many years of trying and failing, they have only one option left.

They have to kill each other. And their anniversary trip to Hawaii seems like a perfect time to do it.

Scenic cliffs, dangerous wildlife, and treacherous waterfalls are ideal situations for accidents to happen. Not to mention, there’s plenty of hiding spots for a well-placed hit man.

They have it all planned out, and neither is any wiser to the other’s devices.

As they get closer to their goal, their bond deepens. Falling in love again wasn’t in their plans…neither was the hit man going off grid. Now the couple must work together to save their marriage from the―literal―brink of death.
