This is solid middle-grade realistic fiction that handles adoption, sibling relationships, and childhood worry with warmth and authenticity. It's not flashy or trendy, but it does what it sets out to do well.
The science project angle gives kids a concrete example of creative problem-solving, and the friendship trio feels genuine. The adoption from China is treated matter-of-factly, which is refreshing—it's part of the story without being THE story.
That said, this is gentle, character-driven stuff. Kids who need constant plot momentum or fantastical elements will get bored. But for the right reader—especially one navigating sibling dynamics or family changes—this hits the spot. The 4.5 Amazon rating suggests it resonates with its audience, even if it's not going to light the world on fire.
