One night. One item. One last heist.

After searching the world for clues and ingedients, Tris is one item away from crafting the Veil’s most powerful artifact: an Infinity Potion. Good thing she knows just where to find one.

The annual Flower Festival is coming up, and the guards protecting the Crystals will be celebrating as well. All she has to do is go to the festival, make some small talk, then slip away to grab the Crystal. Easy, right?

When Tris’s plan goes awry and a forgotten evil attacks the Festival, Tris must choose: the ultimate prize, or the lives of those around her.
