Cassie has been learning on a laptop at home due to COVIID-19 but once again, things are changing. Vaccines are available and infection rates are declining, allowing schools to reopen. Going back into the school building means that Cassie, her family, and friends must readjust once more; while some things are the same, other things have permanently changed.

In this second installment of the Cassie's Big Change series, Cassie and her crew transition from learning on the computer at home to once again sharing the educational experience in the classroom. Peek in on the first days back in the building, how COVID changed life for Cassie and her friends, and the tools their teachers give them to manage their thoughts and feelings during this big change.
