Lucy Prebble

This is your brain on love

Tristan and Connie are guinea-pigs in a clinical trial for a new anti-depressant. Locked-in for the duration of the trial, they develop intense feelings for each other, but is it love or a side-effect? Does it matter?

Exploring the euphoria of love and the terrifying hopelessness of depression, the limits of medicine, scientific objectivity, neurology, guilt, loyalty and sex, Lucy Prebble’s The Effect asks us, are we more than the sum total of our chemistry?

Can you tell the difference between who you are and a side-effect?
