    They were tiny men, dressed all in green. Nobody but Frances saw them, so her cousin Elsie painted paper fairies and took photographs of them "dancing" around Frances to make the grown-ups stop teasing. The girls promised each other they would never, ever tell that the photos weren’t real. But how were Frances and Elsie supposed to know that their photographs would fall into the hands of Sir Arthur Conan Doyle? And who would have dreamed that the man who created the famous detective Sherlock Holmes believed ardently in fairies— and wanted very much to see one? Mary Losure presents this enthralling true story as a fanciful narrative featuring the original Cottingley fairy photos and previously unpublished drawings and images from the family’s archives.

    Because she was going to study him, she decided to call him Alex--short for Avian Learning EXperiment. At that time, most scientists thought that the bigger the brain, the smarter the creature; they studied great apes and dolphins. African greys, with their walnut-sized "birdbrains," were pretty much ignored--until Alex. His intelligence surprised everyone, including Irene. He learned to count, add, and subtract; to recognize shapes, sizes, and colors; and to speak, and understand, hundreds of words. These were things no other animal could do. Alex wasn't supposed to have the brainpower to do them, either. But he did them anyway.Accompanied by Meilo So's stunning illustrations, Alex and Irene's story is one of groundbreaking discoveries about animal intelligence, hard work, and the loving bonds of a unique friendship.
