The Exo Project got a review from VOYA Magazine. (VOYA stands for Voices of Youth Advocates.) I couldn't be happier with the review. It's not online, so I can't link it, but I can share some quotes:
"The Exo Project has a weird, fantastical premise that works very well in DeYoung’s execution. Readers will be sucked into both Matthew and Kiva’s stories as the teens are forced to take on responsibilities that neither wants and struggle against forces beyond their control...In addition to its entertainment value, the book’s greatest strength is its willingness to take on such issues as climate change, bigotry, sexism, violence, and responsibility for the common good."
