Trick or Cheat? (The Alien Next Door, Bk. 4)

Harris can't wait for Halloween and is thrilled with Zeke's "costume," which is just his true alien form. Zeke then uses his powers to create the best costume Harris has ever had, but Roxy feels left out, as she and Harris usually make their costumes together.

When one of the other kids at school gets jealous of Zeke's costume and plots to sabotage it, will Harris and Roxy be able to stop him and help Zeke win the school's costume contest?
