As with most books, your perception of the book is all about expectations. Don’t expect this book to be heavy on technical content; it’s not.
This expectation you should have is this: it is an excellent book for inspiring young minorities to challenge themselves and pursue a higher education in STEM. The book is well written, easy to understand, and easy to read. Setting aside my personal bias and experience in the aerospace industry, I can appreciate that Elio had to overcome certain challenges (particularly poverty and social pressures) to get where he’s at today.
This book is best suited for middle and high school students, particularly those who come from poverty, immigrant, or minority families. However, the book is relatable enough that I believe anyone can enjoy it and walk away with a fresh perspective.
