Chapter 1: Now We Are One

Can’t take my eyes off of you . . .

Motherhood and apple pie

What is love?

When language is so inadequate

Chapter 2: Truly, Madly, Deeply

Love hormones?

The story gets more complicated

Laughter, the best medicine

The whiff of success

Ae fond kiss?

Chapter 3: The Monogamous Brain

Just how demanding can pairbonds be?

Scheherazade triumphant

The mystery in the mind

Chapter 4: Through a Glass Darkly

Rational choice?

How lonely the heart

The Cinderella moment

Showing off

Chapter 5: Saving Face

Something in the way she moves

Faces in the crowd

The sweet smell of symmetry

Chapter 6: By Kith or by Kin

Family and friends

The importance of being networked

Why friendships wane

The costs of romance

When your choice is not your own

Chapter 7: A Cheat by Any Other Name

Breaking up isn’t hard to do

It’s the pain that you feel

Cads v. dads

Trust in what you see

Mad, bad and indescribable

Chapter 8: Sleeping with the Devil

In love with God

Charisma, sex and religion

The God spot

Beyond the edge of despair

Chapter 9: Love and Betrayal Online

Mirage and avatar

Virtual love

Cyberwars

Virtual unreality

Chapter 10: Evolution’s Dilemma

Unpacking the evolutionary question

Putting humans in their place

Hired guns in a poacher’s paradise

Who loves whom?

When did pairbonds evolve?
