A fabulous novel that brings Rosalie Rayner to life, allowing us to sympathize with someone caught in the whirlwind of her times, as well as John Watson, a man cursed, condemned to forever run from his own emotions. Ms. Romano-Lax’s novel commendably sticks close to the available facts. Behave invites us to explore a lifetime of questions about science, ethics, motherhood, sexual attraction, and love.
