When sixteen-year-old Eden Munro agrees to spend the summer with her estranged father in the coastal town of Santa Monica, California, she has no idea what she’s getting herself into. Eden's parents are divorced and have gone their separate ways, and now her father has a whole new family. For Eden, this means she will meet three new stepbrothers. The oldest of the three is Tyler Bruce, a troubled teenager with a short temper and a huge ego. As complete opposites, Eden quickly finds herself in a world full of new experiences when Tyler's friend group takes her under their wing. But the one thing she just can’t understand is Tyler, and the more she tries to uncover the truth about him, the more she falls for the one person she shouldn’t – her stepbrother.

Add in Tyler's clingy girlfriend and a guy who has his eye on Eden, and there are secrets, lies, and plenty of drama. But how can Eden keep her feelings in check? And can she ever uncover the truth about Tyler?

Did I Mention I Love You is the first book in the phenomenal DIMILY trilogy, which follows the lives of Eden Munro and Tyler Bruce as they try to navigate their way through an increasingly confusing world.
