The Surprise Sleepover (The Alien Next Door, Bk. 10)

In the tenth book of the Alien Next Door series, Harris, Roxy, and Zeke finally return to Earth, and decide to show Zeke one last human custom before he has to leave . . . forever!

At long last, Harris, Zeke, and Roxy have finally made it back to Earth. Harris and Roxy are glad to be back on their home planet, but are also sad since now their time with Zeke is over, as he has to go home to Tragas with his family. However, since Zeke's parents have to recharge their ship's power before they leave, there is just enough time left for Zeke to learn about one last human tradition—the sleepover!
