To the Tome of Murder — Lauren Elliott

Three weeks before Thanksgiving, bookshop owner Addie Greyborne already has a full plate -- and a killer on her case . . .
 
Addie's determined to turn a seemingly ordinary November in coastal Greyborne Harbor into one for the books. The windows of her shop display carefully curated works by American writers, including a rare selection of traditional holiday recipes from the influential 19th-century publication Godey's Ladies Magazine. And then there's the town's Civil War-era themed cooking and baking competition, with a hefty cash prize and free publicity going to the winning dish . . .
 
But when she finds her cousin's boyfriend murdered, a stunned Addie reluctantly realizes she may be the only person who can blow the cover off a grisly crime. With so many unanswered questions surrounding the victim's death, Addie must figure out the strange connection between a mysterious vintage briefcase, the disappearance of a first edition copy of Sarah Josepha Hale's famous nursery rhyme, “Mary Had a Little Lamb,” and a dangerously well-read culprit . . .
