We (The new novel by the author of A Winter's Promise) - Christelle Dabos

In a world ruled by “We” each person has a role, a direction, a mission assigned by their Instinct. No choice. No deviation. No freedom. But when some students disappear into silence, Claire, who has always felt out of place, and Goliath, determined to become a Saint before time runs out, find themselves questioning everything. As they follow forbidden trails, escape a murderous Archangel, and discover that “We” is not at all what it seems, all their certainties will be shattered.
