Author Elvira Woodruff and illustrator Adam Rex have teamed up to create "Small Beauties: The Journey of Darcy Heart O'Hara," set in 1840s Derry, as the Famine approaches and threatens to shatter the innocence of the title character. At times heartbreaking but also full of wonder, this book manages to introduce dark themes in an accessible way. ($15.95 / 32 pages / Knopf)
