The Young Avengers return in an epic saga by series creators Allan Heinberg and Jim Cheung! When Billy Kaplan's reality-altering powers begin to rival those of the Scarlet Witch, the young hero sets out on a quest to find her that spans the Marvel Universe and pits Wiccan against both the Avengers and the Young Avengers. But will Wiccan's desire to solve the mystery of his parentage be his salvation or his undoing? With three words, the Scarlet Witch changed the world forever -- and with her return, nothing will ever be the same for the Marvel Universe! This self-contained event reintroduced and redefined the Young Avengers and the Scarlet Witch for the Heroic Age and is essential reading for fans of Marvel Studios' WANDAVISION and AGATHA ALL ALONG!
