Here's a bit about the book from Goodreads:
For seventeen-year-old Flannery Fields, the only respite from the plaid-skirted mean girls at Sacred Heart High School at is her beloved teacher Miss Sweeney’s AP English class. But when Miss Sweeney doesn't show up to teach Flannery's favorite book, Wuthering Heights, leaving behind her purse, Flannery knows something is wrong.
The police are called, and Flannery gives them everything—except Miss Sweeney's copy of Wuthering Heights. This she holds onto. And good thing she does, because when she opens it, it has somehow transformed into Miss Sweeney's real-time diary. It seems Miss Sweeney is in New York City—and she's in trouble.
So Flannery does something very unFlannery-like: she skips school and sets out for Manhattan, with the book as her guide. But as soon as she arrives, she meets a boy named Heath. Heath is British, on a gap year, incredibly smart—yet he's never heard of Albert Einstein or Anne Frank. In fact, Flannery can't help thinking that he seems to have stepped from the pages of Brontë's novel. Could it be?
With inimitable wit and heart, Mary O'Connell has crafted a love letter to reading, to the books that make us who we are. Dear Reader, charming and heartbreaking, is a novel about finding your people, on the page in the world.
Everything about Dear Reader sounds magnificent and I truly can't wait for a chance to read it!
Dear Reader is due out in May from Flatiron Books.
