Librarian Chloe Sampson has been struggling: to take care of her three younger siblings, to find herself, to make ends meet. She stumbles across a rare edition of a book from the 1960s at the local flea market and takes it home with her—only to be shocked when her cranky hermit of a neighbor swoops in and offers to buy it for an exorbitant price. Intrigued, Chloe takes a closer look at the book only to find notes scribbled in the margins between two young lovers back when the book was new…one of whom is almost definitely Jasper Holmes, the curmudgeon next door. And when she begins following the clues left behind, she discovers this isn’t the only old book in town filled with their romantic marginalia. This kickstarts a literary scavenger hunt that Chloe is determined to see through to the end. And she learns that some love stories begin in the unlikeliest of places.
