The personalized Books from Librio are the best on the market! The illustrations are beautifully created and the stories are well written and very imaginative. The personalized characters and stories will entertain my grandchildren for many years. I purchased "The Tree, the Key and Me" for my grandson. He loved it! The book is a large format with fairly large print. The illustrations are beautiful and the story is well written and very imaginative. The personalized character, illustrations, and story are the very best on the market. I also purchased "You, Globi and the Little Lynx" for my granddaughter. She also loved the book, but she did not understand why her book is smaller than her brother's. The illustrations, story, and personalization are beautifully created. Be aware that the book sizes vary by book (I found the size under "More information" on the webpage).
