The First State of Being by Erin Entrada Kelly Review: A Newbery-Winning Time Travel Triumph
The First State of Being is a Newbery Medal–winning middle-grade novel by Erin Entrada Kelly in which twelve-year-old Michael Rosario's life is upended when he meets a mysterious boy from the future. A New York Times bestseller and finalist for the 2024 National Book Award, it is designed to explore themes of friendship, found family, trust, and forgiveness through a time-travel framework — and has earned wide recognition as one of the standout children's books of its year.
LuvemBooks Verdict
Best for
Middle-grade readers aged ten and up — especially those who loved Hello, Universe — who want a high-concept time-travel story that puts friendship, found family, and emotional self-discovery front and centre.
Worth it if
The combination of a propulsive sci-fi premise and genuinely layered emotional themes — trust, forgiveness, first loves, and learning to live in the present — is exactly what you want from middle-grade fiction.
Skip if
Readers who pick up time-travel stories primarily for intricate world-building and hard science-fiction mechanics may find that the speculative elements are firmly in service of interpersonal themes rather than the other way around.
What readers & critics say
Common Sense Media describes it as a "truly endearing novel about accepting the unknown, friendship, and found family" with appeal even for readers who aren't sci-fi fans, praising Kelly's skill in creating believable characters and bringing heartfelt emotion to the story. BookBrowse surfaces a starred review from BookPage noting that Kelly "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."
“This truly endearing novel about accepting the unknown, friendship, and found family has plenty of appeal even for readers who aren't sci-fi fans.”

What Works & What Doesn't
What Works
- Winner of the Newbery Medal and finalist for the 2024 National Book Award, with recognition from multiple respected best-of-year lists
- Praised by BookPage (starred review) for Kelly's skill at addressing young readers' real fears while grounding the story in the power of companionship
- Thematically layered — friendship, found family, first loves, trust, and forgiveness are woven into the time-travel premise rather than treated as background
- Kelly brings the same character-driven sensibility that distinguished her Newbery-winning Hello, Universe, giving the novel an established pedigree
- Designed for a broad middle-grade audience (ages 10+), with a premise accessible enough for reluctant readers and depth to reward thoughtful ones
What Doesn't
- Readers who prefer pure science-fiction world-building over character-focused emotional storytelling may find the time-travel mechanics secondary to the interpersonal themes
- As Kelly's second Newbery Medal win, comparisons to Hello, Universe are inevitable — readers expecting a radically different register from that earlier novel may find the emotional approach familiar
