This is genuinely special. Warga took a premise that could've been gimmicky (robot with feelings!) and made it deeply moving and surprisingly smart about both space exploration and what it means to be alive.
The STEM details are real—this is based on actual Mars rover missions—but the heart of the story is Res grappling with purpose, friendship, and whether he'll succeed. Parents love that it appeals to robot-obsessed kids without violence or chaos. The #1 NYT bestseller status and multiple Best Book awards aren't flukes.
The 'hard-hitting themes' warning is worth noting. This isn't trauma or death, but it does ask big questions about failure, isolation, and mortality that some kids will find heavy. For the right reader—curious, thoughtful, space-loving—this is exactly the kind of book that stays with you.
