Lucy Fitch Perkins 
Cave Twins [EPUB ebook] 

Lucy Fitch Perkins was forty-eight when she was approached by a publisher friend who, impressed by her talents as both an illustrator and writer, which he knew through correspondence, urged her to write. He was so earnest that she thought of an idea for a children’s book the next morning, and she immediately set to work making sketches and preparing the idea for presentation. The publisher came to dinner at their house the next evening and she showed him the idea. His response was immediate "go ahead and write it, and I want it". That book was The Dutch Twins, the first in what became a long running and wildly popular series. Here we publish another in that series, this time the historical ‘The Cave Twins’.
