Turner (The Christmas House, 1994, etc.) pens a generous tale about the small acts of bravery that seal the bonds of friendship. A summer in the mountains with her writer-mother is not Katy's idea of fun, but her attitude changes when sassy and funny neighbor Lena May comes into her life. The two are polar opposites: Lena May is adventurous and brave, while timid Katy is a ``careful sort of person.'' Lena May steadily involves her in several adventures, and Katy finds herself having fun. During one nocturnal outing, the girls come across Lena's beloved grandmother, the only parent she has known since the death of her parents, sleepwalking on the road in her nightgown and talking to herself. For once, brave Lena May is frightened, and it is Katy who must be the strong one. A fully realized rural setting, a community of people in which looking out for each other is expected instead of the exception, and the zeal of Lena May and newly feisty Katythese elements make for a happy story about love, friendship, and a quiet coming-of-age that will have broad appeal.
