“Kelly (also a Newbery medalist, for Hello, Universe) shines when acknowledging today’s readers’ justified fears while showing them that the key to surviving an uncertain road is traveling it in good company. As Ridge encourages Michael to occupy what he calls “the first state of being” — focusing on the here and now, not fixating on a future we can’t control — Michael forges friendships and comes to accept that 'not knowing is part of life.'” — New York Times Book Review

“This short but suspenseful novel is Rebecca Stead’s When You Reach Me meets Tae Keller’s Jennifer Chan is Not Alone. Though it takes place at the turn of the millennium, modern readers will be able to identify with Michael’s anxieties over the future of the world, and find his journey compelling.” — BookPage (starred review)

“A teen time traveler from 2199 visits 1999 and befriends an endearing, anxious tween boy in this wholesome and splendidly entertaining middle-grade novel about embracing the unknown. Kelly has written one of the kindest boys in children's literature.” &nb
