You're trained to save the lives of others. How far would you go to protect your own?

Ruthlessly ambitious Olivia, anxious perfectionist Laura and free-spirited risk-taker Anjali couldn't be more different. Yet their friendship, which began on the first day of medical school, has kept them inseparable for twenty-five years. As wild all-nighters and exam pressures gave way to the struggles and joys of new motherhood and intense jobs, their bond remained unbreakable. Years ago they promised that nothing would come between them and that they'd do anything for one another, including burying one night they have never spoken about: a drug-fuelled university party that forced them to make a deadly choice that could still destroy them.

When an eerily similar tragedy strikes involving their teenage children, everything the three women have built threatens to shatter around them. And they are left asking: just how far can you stretch a friendship before it snaps?
