With stories from NYT bestselling and debut authors, Why on Earth uses an accidental alien invasion to explore love and identity.

What starts as a simple rescue mission for a crew of teen aliens to recover one of their own soon becomes an interstellar encounter no one will forget.

Captain Iona is organizing an impromptu retrieval for her brother, an undercover alien posing as a movie star. But her efforts go awry when a technical malfunction turns her heroic rescue into an unintentional invasion. With tales of disguised extraterrestrials stuck in theme parks, starship engineers hitchhiking to get home, and myth-inspired intergalactic sibling reunions, each story in this multi-author anthology explores the universal desire to be loved and understood, no matter where you come from. After all...aliens are just like us.
