The thrilling finale of the LIFEL1K3 trilogy from the Sunday Times bestselling author of The Nevernight Chronicle and The Illuminae Files.

Best friends have become enemies. Lovers have become strangers. And deciding whose side you're on is a matter of life and death.

For Eve and Lemon, discovering the truth about themselves – and each other – was too much for their friendship to take. As a new world war looms, they must navigate strained loyalties, unlikely alliances, and betrayals.

Heartbreaking choices will reveal the true heroes . . . and they may not be who you think they are.
