Hello, new to the forum so not sure if this is the place to ask but here goes - As a pre-teen around 1985 or 1986 I used to read a book series and for the life of me I can't remember the name of it. I know that it was a mystery/adventure series and the main characters were twins - a boy and a girl. I only really remember the themes of two of the books fairly well. One had to do with cloning and the two main characters were actually cloned and if I remember right they cared for their clones until they passed away because they aged rapidly. The second book had something to do with a wolf and a stranger and maybe even the idea that he could possibly be a werewolf. I believe the name of the series was the last name of the kids and then the word twins. For some reason The Bobbsey Twins keep popping into my head, but obviously that's not it. I know this description is pretty vague, but if anyone here was a kid who read those books during that time or possibly a parent who bought those books I would greatly appreciate the name of the series. Thanks!
Edit - It was a Christian book series. I got them from our local Christian book store.
