Nighttime can be scary. Every bump, thump, or scratch could be a monster lurking under the bed or in a closet. But if that's the case, then why haven't we ever seen a monster? You might think that's because monsters don't exist. But maybe monsters do exist . . . but so do something else: The Night Knights. And when night falls, they take their place, protecting us all from the terrors lurking in the dark. With a lyrical text reminiscent of the bestseller Dream Animals, The Night Knights introduces reluctant sleepers to the many fantastical warriors who will protect them while they slumber, from the Guardians of Gates to the Midnight Flock.
