The Invisible Life of Addie LaRue, by V. E. Schwab
This book is a brilliant, soul-crusher of a novel. Writing in prose at once melancholy and lush--and that makes the most mundane activities, like steeping tea, seem brand new and magical--Schwab follows Addie LaRue through the slow-burn of a love story spanning some three centuries. As she explores the question of what it means to leave a legacy, and what happens if you can't, Schwab dramatizes Addie's frustration with being unable to create, and she leads readers to one of the most epic finales ever.
