The Librarian, by Christy Sloat
He’s from 1892 England, she’s in a small library in 2017. And that's just the start of their troubles.
Emme never meant to stay in Maine. She'd come only to find a librarian for her Gram's library, a custodian for the collection of mysterious books she'd promised to protect. On a dark, wintery night, alone in the library, she takes her first glance into one of the antique novels and finds herself transported to 1892 England staring into the eyes of handsome and dashing hero Jack Ridgewell. As each chapter passes she learns you can truly fall in love with a character in a book, that book boyfriends are real and Emme must choose between the real world, and his.
When the last page is read he's gone and Emme feels the cold loneliness of lost love. Will she find Jack again, or will their love be forever lost? The answer lies within the pages.
