Girl Under Glass is the story of a rootless, rebellious young girl sinking deeper into juvenile delinquency. Given one more chance to avoid juvenile hall, a judge assigns her to community service with a cranky botanist studying plant communication. When he is beaten and left for dead, Kelsey must convince the lead detective that an entire greenhouse full of plants is witness to the crime, and she knows how to prove it.

Girl Under Glass builds on the intriguing science behind The Secret Life of Plants, What Plants Know, The Hidden Life of Trees, and Finding the Mother Tree, all dealing with the cutting-edge research being conducted into the ability of plants to warn other plants of invasions of predatory beetles and certain diseases, and to alter their chemistry from tasty to toxic.
