Sci-fi book about a teen boy that meets an alien boy in human form and becomes friends with him

Question

I read this sci-fi book back in about 1987 in school, at least twice. All I can really remember is it's about a teen boy that meets an alien in human form and they become friends.

In one part, they are in an unoccupied house and I believe the alien was injured and he slowed down time so he could heal. I believe there was a bully involved in the story also.

Been about 34 years since I read it. I'm guessing it was written back in the early '80s. It's not the book Aliens Ate My Homework. Would really love to find it again and buy a copy.

Answer 1

The Space Ship Under the Apple Tree. Here's a very brief synopsis of it from book 2 of the series, The Space Ship Returns to the Apple Tree:

What travels faster than light, but looks like a peanut roaster? Marty's new Bamboozerlergical Metal Martinean Interspacial Superphotic Astral Rocket Disk, of course! The twelve year old from space is back for another summer of adventure with his pal Eddie. This time, the boys want to tour the United States, but there is one small problem--they only have four days to do it and Marty hasn't quite learned to fly his new ship..
