Twisted and deliciously chilling, Greer Hendricks and Sarah Pekkanen's The Wife Between Us exposes the secret complexities of an enviable marriage - and the dangerous truths we ignore in the name of love. Read between the lies.

The Power of Female Partnership As they both approached 50, Greer and Sarah collaborated to achieve their biggest dream - they co-wrote one of the most successful novels of 2018, The Wife Between Us (a 10-week New York Times bestseller) and signed a multi-book publishing deal. Better Together is their slogan (they have it on matching shirts) because neither one could have reached these professional heights on her own. They will talk about how other women, of all ages, can learn to harness the power of partnership - and create a shared space of “psychological safety” - to achieve their own lifelong goals.
In Conversation with Greer Hendricks and Sarah Pekkanen Greer and Sarah will deliver one of their trademark energetic, hilarious, and and honest talks about their origin story and their path through the world of high-stakes publishing and Hollywood.
