Help finding a book

[Yashika]

Hello,
I just want to know the name of the book.
The male lead of the book, spend his 30 years in african jungle being a wild, only to be rescued by a female researcher and is taken back home in new york.
They fell in love in the process. And when the male was supposed to go back to wildness, he return back to her.
I can't just explain the book but the crux is pretty much stated.
If anyone here know or read the book wit similar story. Please drop your answer
I don't really remember the author or book name, but book name has to be start with intial "un-......."

Thanks in advance.
