Reading before bed. Facts at dinner.
Stories shared by our customers.
“Bought these for my 8-year-old who never stops asking questions. She's been reading a few pages every night before bed and keeps coming to tell us random facts at dinner. The books arrived well packaged and look just like the photos.”
“We've been trying to cut down on tablet time and these have genuinely helped. The question-and-answer format is easy for my son to dip in and out of on his own. Ordering was simple and delivery took about the time quoted.”
“Solid printing and nice illustrations. My two kids (6 and 9) both find something at their level, which is rare. Only reason for four stars is shipping took a little longer than I hoped, but tracking kept me updated the whole way.”
“Got the bundle as a birthday present for my nephew and it was a hit. Being able to pick the titles ourselves, including the free ones, was a nice touch. Will be ordering again for Christmas.”
“The explanations are short and clear enough that my 7-year-old doesn't need help with most pages. She's especially obsessed with the space one. Customer service replied quickly when I had a question about my order.”
