Some thoughts:
1. Just so you know, this book is just a bunch of men talking about how sad and lonely they are and telling each other stories. 
2. Frankenstein. Bro. Even if she’s adopted, if you call her “Cousin” and compare your relationship to siblings, you SHOULD NOT marry her. (Especially if someone said they’d come kill her on your wedding night?? Like? Just don’t get married???) 

Jokes aside, this was a wonderful little classic and I really enjoyed reading it!!
