Set just after the events of 'A New Generation', the dream has finally happened. Magic and harmony to all pony-kind has returned to Equestria... but not everything is back to normal. Sunny Starscout is struggling with the loss of her house after it was badly damaged by Sprout, who has gone missing after seemingly being disowned by Phyllis. Whilst her friends work together on the wreckage, Sunny comes across two new unicorns named Lily Heartshoe, and her father, Carter Wrenchbox, who is also Argyle Starshine's former friend, and Sunny must learn that there's more to friendship than she knows.
