This story is a sequel to Lunatic Fringe

After her success as the Princess of Detention, Luna has a half-baked plan to become the Princess of Home-Ec. Life, it seems, has other plans, and she is sent to retrieve a foundling. On her errand, there are lessons to be taught and some others to be learned. But, is Luna the teacher or the student? 

Cerulean Skies has convinced herself that life itself has been forever ruined by her very existence. She is miserable in school and life at home is no better. Crushing poverty has left her a bit cynical, a bit jaded, and some might say that her outlook on life has been soured. She is almost absolutely certain that her very existence has made the lives of everypony around her even worse. Her parents, her brother, all pegasus ponies who have to live on the ground to accommodate her. She came along and everything was ruined.

She might be right.

It doesn't make her questioning of everything any less relevant.

If it wasn't for her idol, Moondancer, she might go insane.

Jitterbug, daughter of Junebug, just doesn't want to work in her mother's garden, because gardens are boring and gross. No, she'd rather go out and have an adventure. After gathering some much needed supplies, she arms herself with her trusty spatula and her pot-lid shield, before sneaking out the back gate to explore the wide world around her.

Along the way she discovers that she has an previously unknown aunt, a giant spider that calls himself Aunt Nancy, and together, they go into the dark and spooky White Tail Woods.

Rainbow Dash's morning was pretty much ruined.
She tripped getting out of bed and landed flat on her face, giving herself an aching muzzle.
She forgot to buy her favorite brand of hay flakes at the store yesterday and had to eat plain toast for breakfast.
She found out she had to pull double-duty today and tomorrow on the weather patrol.
Oh, and she found a nearly-dead foal, broken and bleeding at the edge of Ponyville.

The rest of her day became a whirlpool of stress and worry but the colt woke up, thank Celestia.
Something's not right, though. Nopony can find his parents, he's not in the registers, and there's an unsettling look in his eye...
