Finding love and quenching lust are desires humankind has sought for millennia. Today the internet plays a key role in how we find companionship and connection, but for writer Jennifer Pinkerton - who’s traversing her own ups and downs in love and commitment - this new era of dating apps, omnipresent porn and increasingly fluid identities begs the question: what is the future of modern love?

This one-of-a-kind book blends reportage, memoir, extensive research and lyrical prose to take us on a journey into the heart-scapes of young Australians. Informed by interviews with more than 100 people under 40 - from transgender Aboriginal sistagirls in the Tiwi Islands to conservative Catholics living in Sydney - this book explores the hopes, fears and realities of romantic relationships at a time marked by great expectations and far fewer rules.

Heartland is a probing and insightful exploration of how love, sex, dating and commitment are changing – for better or worse. It gives us a window into the way we live now, and what this might mean for our futures.
