A hilarious alien invasion story with a feel-good message about what it means to be human. Perfect for earthlings of all ages.

When three mysterious visitors from Europe crash-land in Mr. Li's field, he does what any good host would: he invites them back to his farmhouse and offers to help fix up their car. No, there's nothing strange about these guests at all. Just like other humans, they make business, play sportsball and wear hat. As the townsfolk also come to the aid of the visitors and the gathering turns into a little party, interplanetary relations reach an all-time high.

A sweetly funny extraterrestrial offering that explores surprising acts of kindness and acceptance, X. Fang's second picture book is truly out of this world.

E.T. meets cult classic The Iron Giant in this middle grade light sci-fi from Emmy Award-winner Oz Rodriguez and New York Times best-selling author Claribel A. Ortega, perfect for fans of Witchlings.

With a little heart, you can fix anything.

Mimi Perez fixes things. Phones, tablets, speakers, printers. She gets it from her dad--helping him at the family e-repair shop was always one of Mimi's favorite things to do. But ever since Papi was deported, there's a lot more than electronics that need fixing in Mimi's world. Things too big for any twelve-year-old to handle on her own.

Mimi hustles around her Brooklyn neighborhood trying to earn enough money to finally fix her family. There's no time for school or friends, but Mimi knows it will all be worth it the day Papi comes home. Then her ex-friends approach her with a proposition: enter a robotics competition with them, and they could win $50,000. It could be her chance.

Not part of the plan? A mysterious robot crashing to earth. From space.

The robot is scared, alone, and broken, and federal agents are after her. Mimi does what any street-smart electronics repair person would do: she takes the robot home, fixes her up, and in the process, makes herself a friend.

Suddenly, Mimi is anything but alone. She's part of a robotics team. She's sheltering a robot. She's dodging federal agents. And keeping all of it a secret from her mom.

Join a girl and a robot on their life-changing sci-fi adventure in this coming-of-age story that celebrates kids in STEM, first-gen communities, and the power of friendship.

Kim has every reason to be worried, because soon Eila is able to control the minds of everyone around her... in ways she says is the best for everyone.
