An Unexpected Favor

Bilbo Baggins didn't expect to have to raise another child other than Frodo, but one night Gandalf came carrying an elf baby and begging Bilbo to help him. Bella is an elf among hobbits and on Bilbo's 111th birthday, she starts to learn the truth of who she really is. The daughter of Lord Elrond. (This story is still new and I am trying to follow the book events since it will be a little different from the movies.)
