The Historian - The Goblin Archives, #2

Nienna's not a librarian in Portland Oregon. Nope. Not anymore. She's now in another world serving as a Historian to a population of elves. She's obligated to a life of recording her visions in a tome. A tome which seems to be hellbent on recording her death and Alred's heartbreak. Alred Lightvale. Elf. Hot. Protector of the Historian. He's fallen in love with the Historian but he doesn't understand why she won't let him in.
She's trying to keep a dark secret from him and he's hellbent on keeping her alive. And in his life. No matter what dark entity is trying to destroy their world.
