(Litnerd person here). My daughter’s school used Epic, and one of the things we found frustrating was that it was only “free” until 3PM and then if she wanted to continue reading we (the parents) had to buy a subscription (and it was not cheap IMHO). One of the things I love is that this is coming through the school, and will not cost the parents a dime. We cannot expect to impact literacy in lower income households by adding to their overtaxed budgets!
