In 1994, twenty-five-year-old Yuyi Morales traveled from her home in Yelapa, Mexico, to the San Francisco Bay Area with her two-month-old son, Kelly, in order to secure permanent residency in this country. Her passage was not easy, and she spoke no English whatsoever. But due in large measure to help and guidance provided by area children's librarians, she learned English the same way her young son learned to read: through the picture books they shared together. In spare, lyrical verse, Yuyi has created a lasting testament to the journeys, both physical and metaphorical, that she and Kelly have taken together in the intervening years. Beautiful and powerful at any time-but given particular urgency as the status of our own Dreamers becomes uncertain-this is a story that is both topical and timeless.
