THE EQUINOX TEST | Kirkus Reviews

Robot Roz undertakes an unusual ocean journey to save her adopted island home in this third series entry.

When a poison tide flowing across the ocean threatens their island, Roz works with the resident creatures to ensure that they will have clean water, but the destruction of vegetation and crowding of habitats jeopardize everyone’s survival. Brown’s tale of environmental depredation and turmoil is by turns poignant, graceful, endearing, and inspiring, with his (mostly) gentle robot protagonist at its heart. Though Roz is different from the creatures she lives with or encounters—including her son, Brightbill the goose, and his new mate, Glimmerwing—she makes connections through her versatile communication abilities and her desire to understand and help others. When Roz accidentally discovers that the replacement body given to her by Dr. Molovo is waterproof, she sets out to seek help and discovers the human-engineered source of the toxic tide. Brown’s rich descriptions of undersea landscapes, entertaining conversations between Roz and wild creatures, and concise yet powerful explanations of the effect of the poison tide on the ecology of the island are superb. Simple, spare illustrations offer just enough glimpses of Roz and her surroundings to spark the imagination. The climactic confrontation pits oceangoing mammals, seabirds, fish, and even zooplankton against hardware and technology in a nicely choreographed battle. But it is Roz’s heroism and peacemaking that save the day.

Hugely entertaining, timely, and triumphant.
