There are five books in this series, which chronicles the whimsical adventures of a little girl who receives a rare purple turtle. Modi discovers her turtle can talk and perform feats that broaden her perspectives into magical realms of learning and development. Grapie introduces her to a vibrant, mythical world filled with unicorns, mermaids, and other creatures and situations that enrich imagination and encourage a child's intellectual, psychological, and emotional growth - each new experience broadens a child's worldview, making Modi's and Grapie's adventures even more relatable to readers of all ages. It's what makes this series so transformative and unique!
